Have you ever wondered how an automatic transmission works? I did, so I looked it up and then designed this desktop model. It has six forward speeds and one reverse. Real automatic transmissions have a hydraulic or electrical system that engages different clutches and brakes to shift gears depending on the driving situation. With this model you control those simplified brakes and clutches yourself.

The clutch is actuated by sliding the drive shaft through to different positions (which each have two gear markings), while three separate brakes each also have two gear markings. You select a gear by engaging the brake and clutch position associated with your desired gear. See demonstration video: youtube.com/watch?v=-FyC3dn3HJY

I tried to design the gear ratios to be fairly close to what some real cars use, and this is the result, where the input is the crank and the output is the annulus:
1st gear: 1 : 4.29
2nd gear: 1 : 2.5, 71% increase
3rd gear: 1 : 1.67, 50% increase
4th gear: 1 : 1.3, 28% increase
5th gear: 1 : 1, 30% increase
6th gear: 1 : 0.8, 25% increase
Reverse: 1 : -3.93

The OpenSCAD file is included and is highly parametric in case you'd like to play with different gear ratios. If you select a different number of teeth, it will print out the resulting gear ratios at the beginning of the output. I also used Matlab to investigate more thoroughly how the gear sizes affected the various ratios. I used transmission.m as an aid in optimizing the ratios to be somewhat evenly spaced.

This was all printed in PLA at 120 mm/s on a Replicator 1 with Sailfish firmware, default layer height (0.27mm). Everything came out perfectly on the first print. I swear, complex models don't have to be difficult, and who needs glue when you can print snap-fits?

Case for Raspberry Pi.
Derived from thingiverse.com/thing:24945 but with dimensions that fit my Raspbery Pi more accurately.
Wanted to clarify- there were several things I modified:
1) Merged lincomatic's version with latest from Hans.
2) Made the micro USB power connector hole about millimeter taller- otherwise it didn't quite fit.
3) Shaved 0.5mm off from wall which is next to GPIO hole- otherwise it did not fit next to GPIO pins (the pins themselves did fit, but pins have a wider base).
4) also, moved SD card hole a bit. Card reader was in a way of case otherwise.
5) Made the case mating walls longer- otherwise they break too easy.

This case is a derivative of "Raspberry Pi Case" thingiverse.com/thing:30572 designed by redpeppr.

I have added support for four M3 bolts with nut.

UPDATE 2/11/2013

Case as seen in Develop3D Magazine! The STL's have been uploaded to the page again. Please do not resell them without my permission.


This is an updated version of "Raspberry Pi Case" thingiverse.com/thing:24721 that I designed back in June.

This new version fixes:
* RCA Port misalignment
* Headphone port misalignment
* Walls not thick enough for .40 layer thicknesses

Additions:
* Thicker
* Open top for hacking
* Vesa mount bottom

simple cross tweezers. Useful for soldering delicate parts, holding wires etc.

tough-version can be used when more force is required, normal version (less spring force) when handling delicate objects.

Here's a a little design I made up a year ago for 3d printing. The scale here is meant for 1/4 scale dollhouses, that is 1:48 inch scale.

The design is classic 1980's. You can still find this schtuff in thrift stores, and it's still being manufactured for use in hotels, resorts, and cruise ships. It's gentle curves are receptive to frequent reupholstering to allow endless updates as time goes by.

I had this simple 1960's sofa kicking around, and I thought it might be a nice addition to TeamTeamUSA's madiverse collection. I've posted in my favorite working scale of 1:24, but you should scale by 1.5 if you intend to use with the rest of the Madiverse collection.

My name is Dara and I am a teacher at the Brooklyn International High School. All of my students are recently arrived English Language Learners (ELLs). I am lucky enough to have a Makerbot in my classroom. My students and I love to use tinkercad to make our 3-D projects. This is a design that I made for our Hamlet project. It is one of Ophelia's daisies. It is a button that can be sewn onto a felt doll or a story quilt.

This part was made with Tinkercad. Edit the part online at: tinkercad.com/things/68HZNwgyWfX

It's a flower. Perhaps it could be be top of a jewelry box. Perhaps somebody who is good at splicing filament should build this with a different color for each height level. That would be super cool.

This spoon was made to fit exactly 7 grams of my favourite coffee brand. The amount i need to get a perfect cup of espresso from my coffee machine.

The Scad model is fully parametrized. You can easily change the volume (in mm3 steps) of the spoon, for example to measure two teaspoons of sugar, or anything else.

So, you want to make a cup of coffee. Now - you can either shove the coffee into the coffee machine with your bare hands, or you can print out this coffee dosing spoon.

After several attempts for differents container forms I stuck with the cone form, because it was the only one I could get closed at the bottom.

As an additional feature I put a hole into the handle, so after you are finished you can hang it on a hook or a nail.

If your hands are tired rubbing your significant other's sore muscles try this physical therapy tool for soft tissue manipulation. Perfect for force progression for the professional or the amateur and able to be customized to fit your hand for grip in applying either the concave or convex surface.

Based on Emmett's ever popular gear heart: thingiverse.com/thing:12208

This version is about half the width of the original (50 mm), which means its 1/8 the volume and a much faster print (yay math!). i find it takes me ~2 hours to print one (and ~8 for the original)

Rather than just being a straight scaling, this version has been tweaked so taht it will still rotate. The main differences are the number of gear teeth (much fewer, and larger), gear ratio (it now takes 2 rotations to realign, unfortunately) and pins (made much beefier, and they are all one length).

Additionally, there is a hole through the tip so that it can serve as a keychain! Print them out by the dozen and give them to friends/family/cute girls on the bus!

== Edit 6/10/2012 ==
Added a zip of the source plus .stls for every individual component.

Added a "full plate" that prints all the gears + center. Left the pins out, since you usually want to print those with different settings. Fits on a replicator (not sure about others...)

== Edit 6/16/2012 ==
Added a chain connector to gear1 (the top). Updated the src rar (and fixed a compilation bug).

== Edit 6/19/2012 ==
Fixed the length of the pins. Shorted now, so gears should be less wobbly.

This bird whistle, which I got from a friend, in intended to lure Teal and Pintail ducks. My friend received this whistle, his favorite, from a craftsman, who has since passed away. He has not been able to find additional whistles of this style for his children. This is my version of this classic whistle. The pitch of the sound matches the original very well. It is designed for calling birds for observation only. I imagine that it might be a useful device in a post apocalyptic situation.

Carcassone is a tile-laying game. The 'game board' grows as the tiles are laid, in whatever direction the tiles fit. In our games there has been a continuing problem in keeping the tiles straight, and it can become a major operation if the 'board' has to be shifted if it nears a table edge. The Tile Grids each hold nine tiles in perfect alignment, and the grids snap together with small dovetail joints to grow the board in any direction as necessary. There are small raised ridges between each tile, but this doesn't detract from the game. A small game can be held by about ten grids, but a large one with many expansions could take 20 or more grids. The photos show a game as it expands over time.

This is just assembled from the Steve Wall and eM5 parts so that it would all print at one time. Thanks to them for their hard work and research!

This is a part I created for testing support material printing on the Makerbot Replicator. It actually turned up pretty nice! I've noticed the bearing works well for stress relief.

Clip that holds the legs in place when the workmate is folded up.

This is a replacement for expensive clip-less pedal systems used on bicycles. The commercial versions require a special shoe/pedal combination. This item allows you to use any old shoe, and the existing pedal of your bike. Your bike does not have to be modified in anyway. Unfortunately one pair of old sneakers will have to become bike only shoes.

This is an easy way to double your power output when on a bike. You will be able to apply force on your downward and upward stroke. I've notice a big difference while using them.

I've biked 30 miles using this system so far this season. No wear and tear detected. I'll update this later when I've put more miles on.

I always wished they would make this one.

Update: I cleaned up the merged area of the trilego so that a 2x2 block can attach to the bottom. Also added flat (1/3) block STL files.
