It's easier to build a printer if you have good tools, and these screwdriver style hex keys from LDO are great. The set has the common sizes you need:
- 1.27mm
- 2.0mm
- 2.5mm
- 3mm
- 4mm
- 5mm
1.27mm for 2mm screws? Nice.
The screwdriver style lets you apply more torque in a smaller area than you can with a traditional L shape driver- maximize your ugga duggas.
