Hotshoe-mountable holder for Arduino Uno
by bogenfreund, published
This is a carrier plate for mounting an Arduino to a camera. The holder is designed to match the layout of the Arduino Uno (tested with revision 2) and fits into the standardized hot shoe mounting point most cameras feature (usually for attaching flash devices). The carrier plate also has an extension for holding a 9V battery. You can use the holder if you want to connect your Arduino to a camera, for example for building a remote control or similar devices.
I have printed the holder on a MakerBot Replicator with black ABS and standard raft and support. I would recommend to print with the hot shoe side on top.
For assembly, it may be necessary to sand the hot shoe side a bit to better fit the camera. I simply pressed the adapter into the hot shoe which basically had the same effect (some of the ABS came off as it was slightly too high).
You will also need some screws for attaching the Arduino to the carrier plate. The entries are 2,5mm in diameter, and have a depth of 5mm.
The battery can be attached with a rubber band.
I have uploaded the Rhinoceros source file in case you want to make any adjustments.
