comment from costynvd: Just a note about PrusaSlicer. For some reason calculating gap fills takes ages, but isn't needed. Go to Print Settings -> Speed and set Gap fill to 0 to disable gap fill.

Print out one model in white at 5mm for the spacer. Print out a second one in black at just 0.4mm height to use as a top cover.

I used a piece of white baking/parchment paper as the diffuser between the 2 and it works really well. 3 M3 bolts/nuts hold everything in place.
