Battery cover for Logitech EX110 wireless keyboard.
My kids are really hard on keyboards, they recently managed to loose the battery cover for this one, so I designed a new one in scad. The print is ok but orange was possibly not the best colour selection!
The SCAD file is parametrised so might be usable for other battery cover requirements.

An exact replica of the leg of a Logitech G15.

Replacement foot for propping up a computer keyboard. Made this for a co-worker of mine who broke one of the feet on his keyboard.

THE PHOTOS: Are mostly of the OLD design these STLs are meant to pretty-up, but illustrate how to make one without a 3D printer.

WHAT IS IT?
A Chording Keyboard is a one-handed (usually) input device, where you type keystrokes by pressing combinations of buttons. Kind of like playing Guitar Hero. It's also called a Keyer. All the commercially available designs are bulky, old, and stupid, but the basic idea of a chording keyboard is a great one for wearable computing.

I've always wanted to produce this design -- poor guy gave up before everyone on the planet had a 3D printer: xaphoon.com/dataegg/

MY DESIGN:
But my design is nothing of the sort. I put this together a while back, before I had a 3D printer, myself. If you want to go that route, you can... there's no reason to use my STLs, and they're not even complete. So this is basically a very old project I am resurrecting now that I have more resources; but this version is basically the old resource-starved version.

It's based around a Nintendo Wii remote. These things are amazing devices for hardware hacking; the wiimote unit itself contains:
* Several accessable button/switches
* A speaker
* 3-Axis Accelerometer
* BLUETOOTH
* A point-tracking infrared CAMERA. Seriously!
* Vibration buzzer
* Expansion port... with Arduino/ATmega library!!

You can find Wiimotes on sale as low as $15; normally about $30. There is no other way to get this kind of functionality attached to an ATMega/Arduino for twice the price. Probably significantly more.

WHAT YOU NEED:
This little project doesn't even use an ATMega or Arduino (yet) - all you need is a wiimote, some appropriate buttons, and a way to put/hold it all together.

WHAT YOU GET:
The only software *I* am providing assumes you are running Linux, and will only work there. But it would be trivial for anyone with knowledge of their operating system to modify for their purposes; the libraries it relies on are available on all platforms. All you need to do is know how to hook into your OS's input queue so you can imitate a keyboard/mouse.

WHAT IT CAN DO:
* Use the buttons to emulate a keyboard, obviously.
* Use the accelerometer to emulate a mouse.
* All this over BLUETOOTH!

WIP WHY:
* Just until I get some STLs that work for this design. I have future designs already under way but they will be separate Thingiverse projects.
* I'm not uploading the .scad files until I'm done, since Thingiverse refuses to render STLs anymore in a Thing once I've uploaded something it can't render.

ABOUT THE STL:
The STL published is a slightly fixed version of the one in the photos, which has too-thin walls and too little space between index finger and thumb buttons.
