Breadboard Raspberry Pi

I wanted to have a better way of working with various Raspberry Pi models using a breadboard. Thus I created a smaller breadboard plate that can fit a Raspberry Pi 3/4/5, Zero, and Pico. The board consists of three slots that each can fit one type of a Raspberry pi, where each slot has holes for holding the board in place. Each hole is fitted with threaded inserts, which spacers can be screwed afterwards to hold each board.

The table below shows what dimensions of threaded inserts are needed for the holes. The length of spacers is flexible, depending on what distance from the board one would like to what the Raspberry Pi.
