print box and lit in one go, make sure each flat end is down to bed, no rafts, no support, low infill, easy to print, easy to scale to any needed size, in 100% size it fits perfectly for my little eye magnifiers so they dont get dust.
Slicer Simplify settings : layer - start points - use randon start points for all parimeters
this way it will be perfectly round, and all minor errors will be divided all over, so lit will fir perfectly and even turn arround nicely.
