One of my hobbies is programming electronics, so I created a tray that I can move around as needed. The tray is made from ½” birch plywood that is carved out in the middle for Clickfinity plates by NoWarranty (https://www.printables.com/model/452675-gridfinity-clickfinity-baseplate-no-magnets-univer). 

I designed these trays to hold small and large sized breadboards with some storage for small parts to utilize the remaining space.  The small tray is a 2x3 grid, and the large one is 2x5.  They are based on Zach Freedman’s platform: https://gridfinity.xyz/. 

Printing:

Print using any filament. No supports required if printed in the orientation shown.
