Bracket for mounting Arduino Uno or 400p breadboard to size 20 V-slot profile beam.

A bracket for mounting Arduino Uno board (with the original base plate) to a size 20 V-slot profile beam. It can also hold a standard 400 points breadboard.

I used Arduino Uno boards in couple of my projects based on size 20 V-slot aluminium beams. I designed this bracket to keep some order, protect controllers and be able to move my contraptions without loose boards dangling on cables.
It is possible to fit a standard 400 point breadboard on the bracket.
The bracket was originally designed in Autodesk Fusion360.

- This design works with original Arduino Uno Rev.3 board kit which includes a plastic base plate.
- The variant presented here requires access to the end of the beam to be mounted (slid in).
- Due to sligth variations in the design/size of breadboards there may be fitting problem with some of them (however all bords I have fit properly).

Materials and methods

Printing (shown sample):
- Ultimaker 3 with a 0.4mm AA print core,
- material Ultimaker Black PLA,
- stadard UM profile,
- normal resolution (0.15mm),
- printed with enabled supports set to 30%.
- printed with brim (7mm) directly on the clean print bed glas.

Additional materials:
- Arduino Uno Rev.3 kit (with base plate included),
- M5x8 screw + washer + T-nut for fixing the bracket to a beam.
- 2 to 4 M3x8 screws + same number of M3 nuts to fix the base plate to the bracket,
- 2 to 3 M3x6 screws to fix the board to the base plate.

The bracket is printed in two parts. They can be glued together for better stability but it is not necessary. They will lock together when the bracket is mounted to a beam.
