This is my idea of a minimalist build plate "device". I didn't think I needed one, but when I order the super-sticky one, I always had one taking up room on my already small work area.

The knob is made off-center for easy removal/storage of the plates.

I planned on using hot-glue to secure the receiver to my P1S, but oddly, it didn't want to stick to the PLA. So I used double stick tape (for the receiver and the shoes).

I used default settings, PLA, no supports.
