I printed this excellent bearing tray but I wanted to be able to stack more bins on top of it. This lid on top of the tray allows you to stack more bins on top while keeping dust and detritus out of the bearings.
The lid was created in onshape, if you would like to modify it you can do so here: https://cad.onshape.com/documents/bd4f27b23ef53a7e69971fc6/w/da7b3336f3595de125cae66f/
