Now that I have a circuit board for the project, what better to do than use the 3D printer to print an enclosure for its own accessory? I designed a box with cutouts for wiring and a lid in solidworks and 3D printed it.

I will probably end up gluing the board down to the box. Solidworks parts files will be available to download. Please note that some changes might need to be made to get everything to fit together. I designed assuming ideal conditions and ended up having to make the box a little larger (by 0.4mm at the most) in order for the lid to fit on. In its current state, the lid friction fits very firmly in place. Depending on how you construct your board, you might also need to change the spacing of the wiring cutouts.
