8/13/18 Update: New version has mounting holes for Arduino Mega or UNO.
This stand prevents the Arduino and breadboard from dangling off the edge of my workbench and helps keep track of wires for the Pins.
This holds the Arduino Uno and a small breadboard in place.
The breadboard has an adhesive back. I put a few extra holes in the design
to pass wires through, to help keep them organized.
Its a simple Tabbed Box design with open sides and bottom for easy access.
The SVG file is for a laser cutter, parts are glued together with Loctite instant glue.
