Arduino R3/(+Raspberry pi?) and breadboard holder for electronics projects learning

I wanted something to hold the Arduino Uno R3 (in my case, an Elegoo one) along with a breadboard - standard size while learning electronics and arduino basics.

The breadboard I buy have a sticky back which makes a permanent fixture, or you could just hot glue etc.

I've designed this to be printed without supports. X1C handles it just fine.

This is my first upload of my own designs, - I've hung on to lots of others and will slowly add them.

I'm told by a user of this file on MW that this ‘low key fits raspberry pi’..
