Multi-bit Scredwrivers

I needed small, handy bit screwdriver with multiple bits in one. I created several models that differ in how many bits you can insert, from 1 to 4.

I did a torque test, and they all stripped about 4Nm, which is absolutely enough for my use. But I don’t deny that I would like to create an upgraded model that easily exceeds 5Nm. It is however possible that printing with more resistant materials such as PETG, ABS, ASA or various carbon infilled filament the torque is much higher.

Models

• Single bit driver

• Double bit driver

• Triple bit driver

• Quadruple bit driver

Print settings

• Layer Height: 0.2
• Wall loop: 5
• Top/bottom shell layers: 3
• Infill density: 15%
• Support: generally no, but if you have problems on overhangs may be needed.
