Prototyping platform for Arduino-Raspberry

This is a customizable support for electronic cards. It can be adjusted to fit almost any board, with screws fitting or just sitting in a notch.
I made two board, one with an external power supply with rectifier, voltage regulator, volt and amps gauge, a little voltage booster, temperature gauge, a big breadboard and a Uno, and another with the Uno, a little voltage booster, volt and amps gauge, 1602 display and a little breadboard. I fixed some of the boards with screws and some that have no fixing points with a drop of hot glue.

In the customizer you can add as much as 10 boards, in case you need more you have to do some copy and paste...

I used some boards stl files as a reference in the examples, and if you want them you can find them at the following links:
