This is a tiny hollowed-out cap in the shape and size of the iconic TO-92 transistor. I made it to conceal a SOT-23 or SOT-23-6 SMD package on a 3.5×3.6mm flex PCB. Originally the goal was to make something that looked as much as possible like an authentic black-epoxy-resin TO-92, but I was inspired by lee cyborg's amazing alligator clips to try something more colorful!
As you can tell, these prints are tiny. The walls are only 0.45mm thick! I printed these on a Formlabs Form3B in Clear v4 and then dyed them with Jacquard Piñata inks in 95% ethyl alcohol.
