Build plates for the full sized turret chess set suitable for printing the whole set, with both colors, all at once with a MakerBot Replicator with dualstrusion. If you're feeling extra ambitious, I've also included a version with the entire chess board (split in half) as well as all the pieces!

This hasn't been tested yet...

I tried unsuccessfully to properly print out the rockets that were here on thingiverse, so my son and I designed our own in solidworks. I think it was mostly due to learning the limitations of our TOM, and not a problem with the existing designs. You will notice that this is a "all at once" print, where you print the fins, tubes and nose cone all at the same time. There are connecting ribs between the parts so that the fin section will stabilize the other tall thin parts - you'll notice in one of the pictures that the print failed near the end when the tall skinny tubes were tilting around on the ABP conveyor belt.
It is currently just a simple design, but I hope to design a version that will include a mount for a "Spy-pen" camera to take video, and possibly one that will launch gliders when the nosecone is ejected, perhaps a propeller retrieval option for the nosecone - and any other wild ideas my 4 & 7 year olds come up with...
This was printed on a Thing-O-Matic, with a MK6 extruder, ABP (which made the first attempt unstable), the layer height is .35mm, feedrate of 30, and we used white ABS so the kids could color the sections with markers.

Update-
I have added a STL without the connecting ribs - just make sure you have a solid foundation - the incomplete print in the pictures was because the conveyor belt on my ABP was too "floppy" when the parts got that tall.

With these connectors and different lengths of cheap and common 1/2" PVC pipe, you can construct the frame of a personalized Wendy House (or playhouse) for your miniature, chronologically-impaired, humans!

The version I have built, creates a simple, 'traditional', gable-roofed, playhouse frame.

NOTE: The gable end pieces are temperamental when I try to print them. The rotation I have them on the print bed is the only rotation that it doesn't break horribly with. Otherwise, the print-head knocks the model at the top of the tear-drop holes and shifts itself across - creating a geology-like shear across the model

I have included the SketchUp model which shows the sizes of the house. Should you wish to change the lengths of the pipes to scale it up or down for your own use, this model should help if you don't want to just do the maths. (The gable is 45 degrees for ease of trigonometry.)

(And the reason there's two extra struts on the bottom of mine, is that I was intending to wear this hut as part of a costume for Halloween - Baba Yaga's Hut, complete with chicken legs and miniature witch inside. I didn't finish it in time!)

A spaceship based loosely on Queen Amidala's Naboo royal starship from the later Star Wars trilogy modeled in 3ds max.

This is an update to the design. While it may be modded in the future, it is complete and printing. There is a video, here:

Power, Wisdom and Courage... This is my first design in OpenSCAD so, please, don't be evil ^^

Does the world need another earbud holder?

Well, this one fits Apple earbuds and stores the cable neatly.

Lattice models are attractive, useful teaching tools and not easy to construct. The diamond lattice is a traditional example. Diamond crystallizes to form a cubic cell in which each carbon atom forms four bonds. The diamond lattice has octahedral symmetry and the view into each of the 12 edges of the cell is the same.

The Naval Research Laboratory in Washington has long had a Division for the Structure of Matter. NRL hosts a large collection of crystal lattice structures.
cst-www.nrl.navy.mil/lattice/index.html
On one of their web pages I found a downloadable set of coordinates for the diamond unit cell.
cst-www.nrl.navy.mil/lattice/struk/a4.html
As in "Buckyballs" I used a fortran program to make openSCAD module calls. Expand_diamond.f takes the unit cell coordinates of diamond, expands them to a 27 cell cube, and outputs the required calls.

I was surprised at how well the model printed. I recently installed a MK7 extruder which seems to produce cleaner results. There were 276 atoms in the first prints and all but four printed perfectly. Four atoms, two at each of two edges, slanted downwards and did not print well. I removed them from the model and began to get perfect prints.

The picture displays three of the models. The smaller version in the center shows the build surface; the atoms detached from the raft have marks on their surfaces. The larger models are about 65 mm on a side; the one on the right shows a view into an edge.

The fortran program used to generate the diamond openSCAD module calls, expand_diamond.f, is below as are the openSCAD program and the stl output that printed best.

Made it into a plate :)

Using MS-PAINT to make 3D designs? Would Bill have imagined that 26 years ago?

Resized Rhys-Jones large herringbone gear to fit Gregs Accessible while maintaining the original nut and shaft size.

Resized Rhys-Jones small herringbone gear to fit Gregs Accessible and added Gregs small gears hub.

You will need to recalculate your E steps per mm if changing from Gregs originals

New gears are 43:13 (3.3:1)
Gregs originals are 37:11 (3.36:1)

Version 2 has a Countersunk face as suggested by Greg Frost

Version 2_m3 requested by Jolijar ( m3 hex in center of version 2 )

sorry for the german part names
klein = small
gross = large

usable with the wade extruder.

large gear:
teeth: 39
hole and hexagon made for M8 hexagon head bolt

small gear
teeth: 11
hole: 5mm (for NEMA17 engine)
axial hole 2.5mm for M3 thread. (Don't know if this works well. Haven't test it yet)

axial distance: 40mm
Still work in progress :3

Software used:
Inventor 2012 Professional
(Skeinforge44, Sprinter Firmware and Pronterface Host)

Turn your Dremel into a blower or vacuum. It works really well!

.75" ID output port, 2.15" inlet. Inlet bolt circle is 2.438" in diameter, and is for 6 4-40 bolts.

Printed on a Fablicator!

EDIT: The Impeller I believe is backwards. It still works very well, though. I'm going to re-print a mirrored version to see if it makes any difference.

EDIT2: The impeller works about the same despite being right or left handed. go figure.

A derivative of the classic labyrinth game, my "New Art/ New Idea" toy improves upon the original design in that the user now has innumerable game top surfaces to master. With my included .stl file of the maze surface, users can upload, redesign, and print a completely new maze top to be reinstalled upon the existing base. 3-D printing can now push the boundaries of this pre-existing game concept. It’s Thing-a-verse-tastic!

Scout is a printable tribot designed for teaching the Boy Scout robotics merit badge. scouting.org/scoutsource/BoyScouts/AdvancementandAwards/MeritBadges/mb-ROBO.aspx

I've marked this as a derivative of MiniSkyBot because I was inspired by it and because Scout still uses the wheels from that project.

The frame itself is a complete redesign with similar but different goals.

Goals:
Provide a kit that meets the merit badge requirements with parts totaling < $50 USD.

-Minimum printed parts
-Minimum vitamins
-Accommodate an arduino diecimila or nano.
-use a 9V battery.
-Flexible enough to allow boys to improve and extend the design.

The frame is a single printed piece. The tabs for holding the servo motors can be tapped with a 4mm tap to avoid the need for nuts.

The top holes can be tapped with a 3mm tap to screw on an arduino without nuts.

The bracket will hold a 9v battery with just friction. The rear battery bracket has a friction fit cup for a ball bearing caster.

Large holes in the bracket minimize the amount of plastic needed and allow wires to be routed up to the arduino.

Cost
Since affordability was a major consideration, here's a run down of the final project cost.

The plastic cost is just the cost of a roll divided by the number of kits we built. There was lots of plastic left over and the boys are using it to design improvements.

Frame & Wheels $7.86 (plastic from Makerbot)
Tires (2) $2.36 (Hardware store o-rings)
4mm bolts (4) $0.84
wheels screws (4) $0.96
Servos futaba (2) $8.38 (purchased new in bulk on ebay)
Arduino Nano $18.99 (purchased new on ebay)
Ultrasonic $3.90 (purchased new on ebay)
9v connector $0.81 (Radio Shack)
DC power plug $1.86 (Radio Shack)
9V battery $1.25
Total: $47.21

The MakerGame Halloween 2010 Edition. The basic idea is that you can print your own game pieces, tokens, and use the currency of your choice as rewards (3d printed coins/tokens, Halloween candy, or shot glasses of your favorite beverage). This is still very much a work in progress.

I've scaled several Thingiverse models that have a Halloween theme to fit the 30mm Infinite Tile Set so you can get an idea where this is going.

if you are the original creator for these models please feel free to add this version to your thingiverse page and I'll just link to it instead.

A Makerbat redesign to include a attached moon (or mood) ring around the bat. Great for Halloween Jewelry. Use alone for a quick and easy print or snap into it\'s included moon case. You can turn the bat in it\'s moon case depending on your mood or as a sign that it\'s getting late and time to leave the party (see Sleeping Bat pic). Case should be large enough to put in some of your own jewelry or and small LED light.

My maternal Grandfather game me a game like this when I was a kid, but the molded plastic has broken numerous times. I have no idea what this game is called.

I made use of tbuser's 8bit font (http://www.thingiverse.com/thing:2054) for the numbers on the dice. I made no attempt to balance the dice as I do not throw them.

light-weight sturdy model rocket that should be able to take the C6-0 rocket engine/motor easily and fly up high to the CUMULUS!!!

include:
model for body tube w/ motor mount, center rings and fins;
model for quadratic shaped nose cone;

max dimension: ~7" x 7("^2)

MendelMax is a new RepRap 3d printer designed by Maxbots. It is a true reprap, using printed brackets, but instead of using threaded rod for the structural elements it uses inexpensive aluminum extrusions. This gives a huge increase in rigidity for a minimal extra cost (Self sourcing will cost about $50 more than a standard Prusa when purchased from the recommended suppliers). The required extrusions are available world wide from a variety of suppliers.

In addition to greatly increased rigidity, this design is faster to assemble (probably 4 hours for most users), easier to print, has a larger build volume (~215x235x190 if built at the standard dimensions), and is easier to hack on.

Update 2/7/2012: MendelMax full kits and hardware only kits are now available from Maxbots (aka Kludgineer on Thingiverse) @ store.mendelmax.com!

This is a simple demo object. It has gears on shafts inside a shell and would require internal support structures that would be pretty difficult to remove without support that dissolves.

Update: It worked! I've had trouble getting PVA to stick to ABS, however it sticks pretty well to PLA when you extrude both at around 210c. Here's a video:

It is a Rebel Alliance symbol for printing. Rogue Squadron is a starfighter squadron in the Star Wars science fiction saga.

It is made with OpenSCAD, using only simple solids such as cylinders, and cubes.

By carefully adjusting the geometry in a model so that a darker color is under a lighter color by a certain number of layers, it creates a simple color blending effect. With black and white ABS plastic, this allows about 3 or 4 shades of gray between all black and all white. Unfortunately, the effect is minimal on the sides of objects, but on top and bottom it's quite clear. On the side you get about 1 shade of gray between black and white.

This openscad script lets you generate test patterns. By default, it's configured for 0.3 layer height and 1.6 width/thickness. You'll need to modify it based on your skeinforge settings. I bet at higher resolutions with smaller layer heights, you could achieve a greater range.

I bet you could do some really interesting blending if you used translucent PLA! Unfortunately I don't have any 1.75mm PLA filament to test... also, I've only tried this with black and white ABS, but I'm pretty sure it would work with other colors so long as the lighter color is on top.

Note: this test object has an extra layer on top because there's currently a bug with repg dualstrusion where it doesn't print the top layer.

modeling was done in 3ds Max from Autodesk (yay for free student edition), hope the file is 3D printable, merged the teeth/eyes with the proBoolean tools.

Update: Now with a hollowed version (also sltightly updated geometry) :) 3ds Max STL check says it's ok, hope it works

My Parametric Box is like this Thing. thingiverse.com/thing:3938
But I completely rewrote it in OpenSCAD. You can define the height, the diameter and the number of sections you want. This design needs no screw, I have used tbusers pin connector. thingiverse.com/thing:10541 So if you want to edit this you will need to download his pins.scad.
The box in the stl file has a diameter of 80mm and a height of 20mm and 6 sections.
I have added an option to switch between pin or M3 screw connection.

My first post here. didnt find it so i made it

I noticed a startling lack of small projectiles in my office. I also noticed an abundance of 20mm calibration cubes. Solution: Desktop Tebuchet.

Video Demo: youtube.com/watch?v=kW5KLmR86kk

Things are HEATING UP! (to 265° C in its dual extruder arms)

Heads will ROLL! (off the automated build platform after they are finished printing)

REPLICANT - g is an open book; instead of smiling or frowning it just prints what it is thinking. It can take on many forms, and can impersonate anyone. It also can print new sneakers for itself when they go out of style.

Design and print as many faces / expressions / customizations as you want and plug them into the automated build platform- to print a head that fits just print out the short pegs by Tbuser on Thingiverse and mod the head to fit on the peg. Attach to the hole punched out in REPLICANT -g’s automated build platform.

Also 3mm filament should be chopped and placed in the back of the arms and connected to the body in the 2 small holes in back.

Print REPLICANT - g in UV reactive green because that is what the g stands for (also gangster, gcode)

If you print in red it will be REPLICANT - r , if you print in blue and black he will be called REPLICANT - b&b

thank you Tbuser of thingiverse and also Bothacker for the skull version I show in the pic- (also Steve Colbert in the second image)

I have started uploading heads that fit inside - all you need is to print a small peg from Tbuser's bot toolkit and it should attach to the hole in the ABP

I'm a total noob here - to thingiverse and thing-o-matic, but I tried to stay within the guidelines of the bot challenge.....because I want a thing-o-matic...............badly!!!

9-26-11 Bre's head has been updated to have a centered hole in the bottom- sorry about the last one, I think the booloean must have nudged off center before I exported it.
