3D Printable Laser Diode Press Kit for TO-5 and TO-18 Laser Diodes and 12mm Modules

I've been tinkering with 3D design a little bit and decided to make something useful for the community. After a few tweaks and some trial and error I have working designs for both TO-5 / 9mm and TO-18 / 5.6mm laser diodes. Since they're made from plastic they're certainly not as durable as the metal ones but if you break it then you can just print another! I have found PLA+ to be the best filament so far. PETG was too spongy. I think polycarbonate will work even better but I don't have any yet to test with. Ensure the diode is centered perfectly and gently press the diode until you feel it stop moving or you will start to squish the press and deform it. The TO-18 press is much more delicate than the TO-5 version. Let me know if you have any questions.

My print settings were:

.15mm Layer Height
Mininum Perimeters: 2
Solid Layers - Top: 4 Bottom: 4
Minimum Shell Thickness: .2mm
Infill: 100%
Top and Bottom Fill Pattern: Concentric

These are awesome. I will be printing a few out tonight. What are the chances that you could design a diode extractor press?
