I recommend printing on a resin printer. I print them on a Photon Mono 4K at 0.050mm layer height or 0.020 for less post-print polishing. For best results sand the rim of your print until smooth using 1000, 1500, and 2000 grit sandpaper then polishing using beeswax or another safe polishing compound.
