My students and I love the LilyPad, but we want to be able to move the LilyPad from project to project without a lot of hassel or having to destroy our handywork. The solution? Add a makerbotted holder with magnets and snaps!

One magnet is placed under the LilyPad. the other magnet sandwiches the material and the holder to attach the LilyPad to the project.

The JelTone is a (partially!) edible toy piano made for the Gowanus Studio's Jell-O Mold Competition, and also shown at the Solid Sound Festival. Check out the videos: moonmilk.com/2011/07/09/meet-the-jeltone/

Design and construction by Astrida Valigorsky, Ranjit Bhatnagar, Mimi Hui, and Catarina Mota.

Inspired by an item in the video-game, Deus Ex: Human Revolution, which totes itself as Cyber-Renaissance in art style, what we have here is a printable, good sized, glow-stick candelabra to bring a little neo-noir class to your home or work.

(In game, you'd find the relevant prop in Jensen's apartment.)

27.5cm (10.8") tall without glow-sticks
40cm (15.7") tall with glow-sticks installed.
152g (5.4oz) of plastic, printed and trimmed.
8hrs (approx) printing time.

I had to take a few liberties with the design of the 'candle holding cups' for easier printing - those flat gentle curves couldn't survive without support. Instead, I went for a sharply faceted holder, which I personally prefer - I like the low-poly look.

What self-respecting nerd wouldn't have one of these things lying around? Originally, I wanted it to be solar powered, but I had to settle for AAA batteries. I scavenged the motor and propeller from a 6 in 1 educational solar kit. There's no reason why you can't print your own propeller and use a motor from a cd player or really any motor.

Snap together 3D printable truck-like robot. Unlike the cool-but-ultimately-non-functional Tank designs ( thingiverse.com/thing:6554 and thingiverse.com/thing:8080 ), this bot actually works. Sadly the motors could not generate enough torque to actually move the tank robot due to the amount of friction introduced by the worm gear and tank treads. Encouraged by the success of my 27 to 1 Reduction Gearset thingiverse.com/thing:9414 I designed this bot from the ground up to be low friction, snap-together and almost entirely 3D printable. The only non-printable components are the motors, the motor mounting screws, the batteries, the wire and the nuts that serve as contacts in the battery holders. I hope to upload some PCB mounts soon so you can easily add the electronics necessary to make this bot autonomous, but if you are impatient I recommend looking into NBitWonder's awesome DC Motor Driver thingiverse.com/thing:7618 which was designed for the tank-bot.

I used this script to design the gears: thingiverse.com/thing:3575 (You will need to download the scad to use the attached truck.scad file). I also used this script to generate the battery holders: thingiverse.com/thing:5079

As you can see from the video, the left rear axel isn't spinning freely and needs some sanding/filing.

UPDATE:
I fixed the drag on the left rear axel by replacing "axelholder.stl" with "wheelholder.stl" in conjunction with "axelend2.stl".

NOTE:
This design is based on the tolerances of my cupcake 3D printer. As several folks who printed out the 27 to 1 gearset pointed out, the Thing-O-Matic has much better tolerances, so some of the snap-together parts may need some glue (or openscad tweaking) if your printer is better than mine!

Printed Parametric Chainmail

I've been wanting to try this for a while. This is a sheet of interlocking rings, printed in place. The rings are basically square, with cut off corners. Two sets of diagonals cross each other at different heights, with four posts at the corners. Well, it makes sense when you see the pictures!

This is the first thing I've designed in OpenSCAD, so the code is probably pretty sloppy. The major parameters that can be changed are the layer thickness and line width, along with ring size and number.

I searched for "chainmail" on Thingiverse and the only result was a post by Vik on the Interlocking Rings thing: "Next, chainmail. Right?" So I hope you like this, Vik!

This is a Collaboration between MakerBlock and I for the MakerBot United Competition. And we now have a new collaborator syvwlch! If you like it, please click the 'like' button!

These are a set of Windup ChatterBox Teeth, like the kind you get in gag stores or the kind "The Joker" always seems to have in "Batman". The two toned teeth are of course achieved by changing the filament at the proper time during the print. The wind-up portion is driven by a clock spring, which you can get from any old wind-up toy (or a wind-up clock, but why would you want to destroy a clock?). I got this particular clock spring from a Dollar Store Easter Toy, you can see the pictures of the Harley Riding Easter Bunny I sacrificed in the instructions.

The Drive Mechanism is a Geneva Drive, which is pretty common for a wind-up toy. You wind up the spring and it rotates a cam shaft, opening and closing the teeth. Unfortunately, we could never get the mechanism to work properly. The teeth chatter of course, but the problem here is they chatter too fast and the clock spring expends its energy WAY too fast. We still have a few days left in the competition, so if anyone thinks they have a solution for this and would like to collaborate, speak up now!

We have tried every thing we can think of and are at our wits end. We thought gears would produce enough friction to slow the clock spring down, but they don't!

This is a 3D-printable version of the Penrose Triangle illusion, based solely on the 1934 design painted by Swedish artist Oscar Reutersvärd. The design also appeared on Swedish postage stamps in the early 1980s.

I created this 3D design entirely from scratch using the process outlined in the "Instructions" section below. This work is based solely on Oscar Reutersvärd's design, although some elements are inspired by the Hollow-Face illusion discovered many decades (if not centuries) ago.

This model contains a number of notable improvements over previous 3D representations:

1) It is parallax-corrected for a viewing distance of 40cm, i.e. it will look exactly like Oscar Reutersvärd's design, with cubes lining up on all 3 sides simultaneously. This is a great visual improvement over previous versions, which only lined up on 2 sides simultaneously.

2) It has been resized (to 99.43 x 99.65mm) to make maximum use of the Makerbot build envelope.

3) The top edges are now tapered so as to make the most of your printer's capabilities. The better your printer, the sharper the edges will be.

4) I own the copyright to this 3D design, and hereby distribute it under the "Attribution/Non-Commercial/Share-Alike" licence for all non-profit parties to print, improve and share.

Super easy shape. Maximal Derp all around.

Most soap in the world is provided in the form of bars. Bars, that are deployed on grids or basins, that inevitably turn into a rather filthy, slimy affair.

This soap bar dispenser works differently. The soap bar is never in contact with water. Using the sled, you shave off flakes of soap from the bar.

(Note - the dispenser in my picture was aborted in mid-print, because I ran out of ABS and changing the spool did not work as expected. The model dispenser is higher, and the scad file is parametric anyway.)

This thing is public domain, because caring is sharing and I am counting on the thingiverse hivemind to make this more awesome. Feel free to flattr me or any derivatives if this is useful for you.

This edge lock system for paper and plastic works great for realizing meshes from thin sheets of material. It avoids the negative accumulated error common with the classic glue and tab method of construction. Instead the edges have enough freedom to adjust towards the perfect position.

This OpenSCAD script provides modules for both Spur and Bevel Gears. It has some major enhancements over my original gear script thingiverse.com/thing:3534. It uses some of the spur gear nomenclature code from TheOtherRob github.com/TheOtherRob/MCAD with my own code for generating the involute teeth. The bevel gear is also my own work. Thanks also to elmom for some enhancements to my original gear script thingiverse.com/thing:3547.

Enhancements include the Bevel gear module, backlash settings, parameterised number of facets for the involute curve and whole of tooth generation to avoid some of the issues the original script had when mirroring a half tooth.

The STLs provided are not intended for direct use, but instead show examples of what can be done with the parametric script.

Parametric Involute Spur Gears take the following parameters:
number_of_teeth
circular_pitch or diametral_pitch: controls the size of the teeth (and hence the size of the gear).
pressure_angle: controls the shape of the teeth.
clearance: The gap between the root between teeth and the teeth point on a meshing gear.
gear_thickness: the thickness of the gear plate.
rim_thickness: the thickness of the gear at the rim (including the teeth).
rim_width: radial distance from the root of the teeth to the inside of the rim.
hub_thickness: the thickness of the section around the bore.
hub_diameter
bore_diameter: size of the hole in the middle
circles: the number of circular holes to cut in the gear plate.
backlash: the space between this the back of this gears teeth and the front of its meshing gear\'s teeth when the gear is correctly spaced from it.
twist: for making helical gears.
involute_facets: the number of facets in one side of the involute tooth shape. If this is omitted it will be 1/4 of $fn. If $fn is not set, it will be 5.

Parametric Involute Profile Bevel (Conical) Gears take the following parameters:
number_of_teeth
cone_distance: The distance from the pitch apex to the outside pitch diameter.
face_width: The length of the teeth.
outside_circular_pitch: The circular pitch at the outside pitch diameter.
pressure_angle: Defines the shape of the teeth.
clearance: Gap between the tip of the teeth on one gear and the root of the teeth on another meshing gear.
bore_diameter: The size of the hole in the middle.
gear_thickness: The thickness of the gear for bevel_gear_back_cone finish (see below).
backlash: Makes the tooth width smaller to make a gap between teeth of correctly spaced gears to allow for manufacturing tolerances.
involute_facets: As for spur gears.
finish: Specify either bevel_gear_flat(0) or bevel_gear_back_cone(1). If you don't specify this parameter you will get a flat gear for pitch angles less than 45 degrees and a back cone gear for pitch angles greater than 45 degrees. The example shows both with the small gear being the flat one.

Update: v5.0 Implements backlash for bevel gears (This was not working in v4.0).

I wanted a little dock to put my phone on that plugs right into the wall, so I don't have a cord dangling over my two dogs' beds to my nightstand, where they could possibly trip on it and send my phone flying.

I whipped this up in sketchup in 5 minutes, printed it out, cleaned it up, and added the cord. The block goes into one part and plugs into the wall, and the connector wraps around and goes into the slot.
