Gamebit security bit driver for 4 mm screwdriver

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.

Print instructions

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.

Notes:

Print pointing UP, with the part that goes to the screwdriver at the bottom. I used normal PLA.
