I needed a 49mm lens cap for my Raynox-250 macro lens to go with the rear cover I designed earlier.
After print, place the cap with button towards a hard surface and push firmly until it snaps loose. Do the same for the other side. There’s only a 0.3mm gap in the design so it will probably stick together somewhat. I’ve printed in 0.15mm PLA.
