Space Base Player Boards - Dovetail - Prusa Mini size!

I wanted a less complicated attachment mechanism and didn't want to deal with magnets, so I used prusaslicer's built in cut feature to add a dovetail joint.

Because I only have a Prusa Mini, I also had to make sure this fit on the bed (it was close). 

removed magnet holes, combined in slicer into one monolith, then used the cut tool with dovetail to split back into 3 pieces that all fit on a Prusa Mini bed.
