This light tube is the perfect project for those nice summer evenings. Instead of going through glow stick after glow stick, make your own gigantic light tube! Mix and match your own colors of plastic and LEDs to get unique effects.

Lasts for ~20 Hours!

This project is perfect for kids, no soldering required! Using the unique design, just stuff some aluminum foil into the Base, push your LED and Resistor into the foil, insert your battery into the Holder, and push together.

All you need for this project is:

• LED
• ~300Ohms Resistor for White/Blue LEDs, ~370Ohms for Red/Yellow LEDs
• 9V battery
• aluminum foil.
  Some glue probably wouldn't hurt either. Check out the instructions for more details.

Modular Icecube trays!

These modular blocks allow you to make any size icecube tray you wish. Keep them seperate and fill up all the empty nooks and crannies in your freezer, or make one gigantic tray to take up a whole shelf! Its up to you!!!

Submitted for the IceboxChallenge
https://firstbuild.com/bongoboy23/modular-icecube-tray/

Features:

-The holders allow for easy ice removal with a exposed bottom push-pad. No struggling to get those icecubes out!

-Icecube models designed for flexible plastic! Use your cool new Ninjaflex or Bendlay plastic to make easy-to-eject icecubes

-Don't have Ninjaflex or Bendlay? Not a problem. Print out some icecube molds, pour in some silicone rubber and make a super durable, water-tight icecube mold.

-All Icecube models have draft! This serves a dual purpose of making it easier to get the icecubes out, AND make it easier to remove from the molds.

-Update (11-28-2014) - Case V2 has small grooves on top and bottom for easier stacking of icecube trays.

Types of molds!

• 1 Large Cube
  4xSmall Cubes
  4xSmall Hexagons
  1 Large Rod/Cylinder
  1 Half Sphere
  1 Star!!!
  1 Tube-w-Hole (Added 11-23-2014)

Models are freely available in the downloads. If you can't open/import Autodesk Inventor models, just let me know and I will be happy to provide steps, iges, etc. Just let me know what file type you would like to see and I'll add it to the downloads.

Any additional icecube designs are more then welcome! Share your custom icecube tray, and I'll be sure to post a link here!
(Be sure to link this as a source or send me a message so I know about it)

~IMPORTANT NOTE

As with all 3D printed objects, it is important to know what is food-safe and what is not. For any 3D printed part that is in a food environment and/or comes into contact with food, it is highly recommended you apply a food safe sealant to prevent the spread of any possible toxins in the plastic, and prevent the growth of bacteria on the many visible & non-visible cracks/crevices that are inherent with 3D printing. Usually you can use Silicone sealant or a Polyurethane (make sure its food safe!) spray on coating.

Even if you don't print this 3d part out, please take this advise with you as you look around at other models to print. Safety first!

UPDATE 11-23-2014:
-Added Tube-w-hole. Just the tube, but with a hole down the center for greater surface area.
UPDATE 11-29-2014:
-Added demonstration picture of silicone mold! Turned out perfect! Some notes. Came out pretty easy, but I think I may make a little shake table to get some of the bubbles out. I just knocked it against the table for a few minutes. Bubbles were really just on the top, and not inside, so still works great.
Another note, Will probably make the square in the top bigger, to make it easier to pour the mold around the internal shapes to help prevent bubbles forming.

Printed for the IceboxChallenge!

*3d printed part pictures to be added soon. Currently printing parts now, wanted to make sure submission was in though.

*More versions of dividers/circles to be uploaded soon. Dimensions of pegs will also soon be coming as detailed drawings, for those who want to design dividers/organizers.

Modular Shelving units!!!

Keep the stuff in your fridge organized with these sweet modular shelves.
Features easy to pull out drawers, configurable dividers & organizers, and a super sturdy design.

Drawers can be configured and reconfigure with ease, just drop in your dividers to make any size section, or stick them on the front row and apply labels as needed! No more looking for lost jar, easily identify whats where. Also available are varying circle cutouts. This lets you easy keep jars, spices, pretty much anything round, in place as you pull out drawers.

Bases can be stacked both up and down, and left to right. Drawers lock in only from the front, so when you pull a drawer out it doesn't come tumbling down!
Bases come in multiple sizes, and can be used with a single spacer, to give you added height (Using the limited dimensions from IceboxChallenge)

WORK IN PROGRESS
Status - On Hold

Currently working on improvements, including: Square for better screwing/unscrewing. Tube in bottle for better airflow when dispensing. Possible use twist valve instead of one way valve for better airflow. Illustrated assembly guide with step-by-step instructions for easy/clear/frustration-free assembly.

Check back soon, current plan/timeline has these improvements all done by end of IceboxChallenge (Nov 23rd) .

Suggestions are always welcome! Help me develop this into something really cool!

This is a adjustable bottle stand with dispensing nozzle for putting in the fridge.

This super cool stand and dispenser means you no longer have to take out your 2 liter soda bottle, unscrew the cap, pour into a cup, screw the lid back on, and add ice to your drink.
With this, you can just open the fridge, push a nozzle, have have a cool refreshing beverage dispensed straight into a cup!

<->FEATURES<->
-Adjustable stand for fitting on any shelf in your fridge! No worries about if the bottle will fit, this stand gives you a nice range between 0 to 60 degree bottle angle.
-Soda Dispenser head, fits a standard 2 liter bottle cap, and mounting to ensure it can be used multiple times*
-Soda dispenser has one way valve to help airflow into the bottom while dispensing, and keep carbonation in when not!

Soda Stand

• The first part is an adjustable stand, sized to hold a 2 liter bottle. Includes:

• Holder comes in two version, the nice big strong version (large half circle), and the plastic-savers version (several long ribs).

• Base, large footprint to ensure no bottle tip over, and slots for stand engagement.

• Stand & ClipHolder. This mounts on the bottom of the holder for easy adjustment of bottle angle.

Soda Dispenser Nozzle

• Nozzle for dispensing soda. Angled to keep the nozzle as close to horizontal as possible. I.E. if the bottle is at 30degrees, nozzle is level, if at 60degrees, nozzle is only 30degrees off horizontal. Also included is one-way valve hole for better airflow.

• Cap Holder designed to fit over standard cap. 4 smaller holes ensure that continued tightening/untightening doesnt break any seals around the cap. Internals also designed to easily drain liquid inside the part, for easy washing and cleaning.

• Angled Section includes one way valve hole, to better replace dispensed liquid with air.

• Nozzle holder holds a standard nozzle of amazon, with enough room to tighten nut on inside for excellent sealing.

If you need any more files or details, feel free to comment, I will try to respond as soon as possible (may be several hours at least, and even longer during work hours)

Check back as I add more animals!

I have changed one major thing and several minor things on the original design.

Major change - The original gear on the Makerbot meant for gripping the plastic can be used on this extruder. This translates to superb grip compared to using only the screw's threads to grip the plastic.

Minor changes:
-Flipped the mount, so Stepper motor doesn't run out of cable length.
-Extruder holes moved, mounts DIRECTLY onto the Makerbot.
-Small gear center hole larger to fit on Makerbot's Stepstruder motor.

The increased grip added to the geared extruder means you can get up to some nice speeds on your Makerbot!

Better Pictures coming soon!

IMPORTANT
Check back for updates as I revise the files

This is an amazing blooming flower! Turn the gear on the bottom and the flower blooms, exposing the beautiful flower within!

Original purpose for this design was creating something to turn rotational movement into linear movement, using something that could be printed on a Makerbot. Figured the easiest to design was something screw-like, but with overhang restrictions, I was unsure whether a tight screw design would work. And it turns out it does!

DESIGN VERSIONS
There are two different versions.
First version uses glue and filament as the hinges for the petals. Pros to this is the petals are much tighter, and don't wiggle around alot. Con is that it requires more glue.
Second version uses links as the hinges. Pro is that less glue is needed. Cons are that it wiggles alot more, because the links require some give to snap into place. Also, when snapping into the base, the base links have a significant chance of breaking off. I have added supports and fixes to prevent this from happening, but there is still a chance. Extra stl for broken links to glue on in case this happens.

DIFFERENT GEARS
NOTE: Applies only to large flowers
In order to turn the gears, I designed two different gear systems.
First version allows the entire bottom to turn, but is more difficult to get on the base.
Second version is easier to get on, but the gear is slightly more difficult to get to, and could prove more difficult for some people to turn.

FILES
Files are placed in zip files, for easy organization.

Credit where credit is due, flower in center is from:
http://www.thingiverse.com/thing:5883

Internal screw is 1 rotation per 20mm rise.
Design files included.
(I apologize for the messy designs, didn't organize or rename anything in the ipt files :P )

NOTE:
For those who want to design a different center piece without the cap, the rod in the center is 5mm diameter. This way you can design the hole directly into your variation.

UPDATES

UPDATE 7/7/2011:
Edited Version 1-Large Flower-Base updated.
EDITS: Forgot to edit the top ring of the small petals, they were 1mm too wide. Also the main circle of the base is several millimeters too small, causing the small petals to be too close to the center shaft. Sorry to those who have already printed this.

UPDATE 7/8/2011:
Edited version of Gear 1 for Large Flower uploaded.
1 zip with all current STL Files as of 7/8/2011 uploaded.
EDITS: Center shaft is not long enough on Gear 1 bottom (Gear 2 is fine). Really sorry I missed this.(Note it says v1, but it is also for v2)

UPDATE 7/9/2011:
Edited version of large flower petal for v1 uploaded.....hinge was too big....
Re-upload of Large V1 zip with correct STL Files.
Revised version updated.

UPDATE 7/12/2011:
Makerbot out of commission ATM, can't test any of the un-built files, but they should work just fine.

UPDATE 7/22/2011:
Hooray! Got my replacement parts, TOM is back up and running, will start printing some new flowers in the next few days!

If you find any other mistakes, please message me.

A simple twisting box, except this one has 4 smaller boxes inside!

Not only does it have separate compartments, but they come apart!

NOTE:
Takes a tad bit of coordination to get them all in at the same time, which is what the optional base is for. Modifications to come soon.

This is a mini-makerbot for your cube farm:
http://www.thingiverse.com/thing:8012

It just wouldn't be the same without your epic 3D Printer, now would it?

ADDED:
Makerbot_V2.stl - Just a few tweaks.
Makerbot_WKeyring.stl - Added a small hole in the top corner, so it can be put on a keychain. Untested currently.

ADDED 6/17/2011:
Makerbot_v3.stl - Made outside columns thicker. Moved keyring hole to bottom, for a bigger and stronger keyring.

ADDED 6/18/2011:
Makerbot_v4.stl - Added Fan holes. Very slightly thicker nozzle.
FileCabinet.stl - Simple 3 drawer file cabinet, by request.

ADDED 6/19/2011:
Makerbot_v5.stl - Added small hole in top for mini-filament. (extrude a little bit of plastic, cut off, glue in mini-hole on top)
-Picture of white v5 with green mini-filament added.

ADDED 6/21/2011:
Makerbotv6.stl - Deeper hole for mini-filament. Mini-USB detail added.
Base(3,4,6).stl - Base for legs
Leg.stl - Legs

-Base and Legs added, make your mini-Makerbot into a mini robot, ready to replicate and conquer!* Or use it to display something else.

*Note that this will not actually happen...Hopefully.

This is a simple tension locking mechanism.

With the new MK6's ability for rapid reversal, the simple tension screw would gradually jiggle lose. And while I know there are several different designs for the new extruders that prevent this, I did not want to take a bunch of time to print and replace the old acrylic frame.

Solution? Design a lock system to prevent the screw from coming lose!
10 minutes to design, 30 minutes to print the pieces, and my quick fix is ready and working!

The name's Bot. James Bot.

Saving the world from market monopolies, this secret agent outfit for your Makerbot turns it into the perfect monopoly-fighting machine. Capable of printing out cups, keychains, and even mini-bots, this secret agent machine will have those massive corporations shaking in their hand-polished shoes.

Give your bot a spiffy tuxedo, and a hand to hold his martini, shaken, not stirred. Or perhaps you would like it to hold a trusty sidearm, ready to save the world (and the girl)!

There were several things I didn't like about this. The first is the spool was too small, so my filament would just unwind itself. The second was that I didn't have any rods to go between the spools. Finally, the hole in the middle was too small for the rod I wanted to but it on.

So what did I do?
Made it extend-able, so the size of the spool can be changed.
Made the center hole bigger.
Made it so I could attached printable hooks to hold the plastic onto the spool (and made them double, so that it would hold more plastic!)

AND, to save myself some plastic, I made the ends with connectors so you can attach them and hopefully get more plastic onto less spools.

Looking for some way to get back at that jerk in the cubicle over? Want to build a legal weapon for self defense?

I introduce to you, the amazing Disk Shooter! With Auto-Reloading capabilities, exchangeable magazines, and a custom machined handle, this weapon of mass destruction will have your coworkers shaking in their shoes!

BUILD YOURS TODAY!

UPDATE 4/16/2011:
Added a new slide, main barrel, and auto-reload base files in a zip.
CHANGES:
-Slide cut down on sides
-Main barrel has catches on the back to prevent slide from coming out the back (Have to load slide through top of barrel, then it won't slide too far forward or backwards)
-Main barrel to Auto-reload base connection changed, now meant to be screwed on, should fit with M3 screws.

-If requested, will upload old version of main barrel with ONLY catches added on, without the screw add-on

This is a different version of my design at:
http://www.thingiverse.com/thing:7416

This version is Ball and Socket version. This version, while a little less sturdy then the simple links, allows for rotation and movement on more then one axis.

Stay tuned for uploads of the different versions of my bracelet, using Ball and Socket connections instead!

EDIT 3/29/2011:
Added Ball and Socket links that parallel original links parts.

EDIT 3/30/2011:
Added Long version of default link

EDIT 3/31/2011:
Added Link-to-Ball and Ball-to-Link pieces, so my two different styles can connect to each other.

NOTE: Re-upload of a design I removed earlier

This is a simple link that can be made in to bracelets (maybe even a necklace!)

Each link can be printed in different colors to create something unique to you!

For added fun, there is even links with letters on them (and one with a star), so you can add your name or favorite phrase!!!

Files:
Bracelet_Base_SM - Default link
Bracelet_Base_SM_Rounded - Circle Link
Bracelet_Base_SM_Square - Square Link
Bracelet_Base_SM_2 - Two-way Link
Bracelet_Base_SM_WLoop - Link with loop to hook stuff (keychains?)

EDIT 3/30/2011:
Bracelet_Base_SM_Long added
-a longer version of the default link

EDIT 3/31/2011:
Added Link-to-Ball and Ball-to-Link pieces, so my two different styles can connect to each other.

An Abacus. For those that want to go old school on their math calculations. Or for when the end of the world comes upon us.

This is a case for this instructable:
http://www.instructables.com/id/How-to-make-a-solar-iPodiPhone-charger-aka-Might/

I didn't like putting it in an altoid case and having to stick the solar panel on the outside, so designed a simple case to hold everything.

The inner walls are to keep things from sliding around, if you dont want to glue stuff down. Lid hooks on solar panel and slides down, which you can then screw in. Use any screw you feel fits, I just made the holes on for the lid to act as lead holes for drilling out better holes.

To fit everything:
Make sure to get rid of alot of the extra solar panel cable, all that extra cable wont fit in the box. Put in the electronics first, then battery on top, then slide the solar panel over top. (may need to be jiggle around to get everything to sit snug).

NOTE:
The lid has built in support for the small flaps that slide into the top of the box. Should be able to snip and twist off, some sanding may be needed.

UPDATE(3/15/2011):
More pictures added for assembly help.

This is a screwing money box.
Lid has 4 slots in it for Penny/Nickel/Dime/Quarter.
Lid also has a P/N/D/Q for each coin next to each slot.
Base is sectioned off so your coins don't get mixed up!

Also included is a normal lid, in case you just want a cool 4 compartment screwing box.

A penguin based off of those toy erasers. Felt like making one with my Thing-O-Matic for my sister.

I kept having problems with big prints shifting on the automated build platform, and I heard it might be because the belt isnt completely attached to the platform. So what I did was create flaps that went over the belt to keep it from moving upward during a print. I have attached them, but have yet to print out a large object. (Also, I have only printed out the middle ones for use, but I also made ones to go on the corners)

I have prints for the middle screws, BLFR (Back-left, Front-right), and BRFL (Back-right, Front-left). Print whichever ones you want depending on where you want to attach the flaps.

NOTE: These flaps COVER PART OF THE BUILD PLATFORM. While it is a very small amount, make sure your prints are small enough that the extruder wont run into these.

EDIT: Someone mentioned that this might stick to the belt after awhile because of the heat. If this happens to me, I will be sure to post it. Also, because the build platform doesn't get as high as the extruder does, only around 125C, I believe it should be fine. Only concern I would have is it might eventually warp from heating/cooling alot.
