I was trying to dissasemble a Gameboy Color clone (GB Boy Colour) and I notice that they used some nasty security screws I did not had a bit for them.
Logically I printed one, and it worked. Since the part is quite fragile, it was only enough for 2 screws, unscrewing them and screwing them back.
Resolution:
0.05
Infill:
100
Notes:
Print pointing UP, with the part that goes to the screwdriver at the bottom. I used normal PLA.
