My silicone mold and resin outcome are always getting broken the + stems, any suggestions on how I can get them whole?
from my experience and from my research, the best way is using the $ynth. however, it is absolutely possible to just use the backside of a keycap. if your issue is in your mold then be sure to degauss, dab silicone into stem, pour slowly, and dont take too long before you put it under pressure. if the issue is with bubbles or uncured/sticky resin, then watch out for moisture, measure accurately, mix completely, and again dont take too long before putting under pressure. good luck and dont give up.
