Pocket ratchet screwdriver for bits (To both Loosen and tighten screws)

The Pocket ratchet screwdriver is a tool that should be in every hobbyists toolbox. Assembled length is 11cm.

It consists of 11 printed parts. The only extra parts you need are two springs from pens.

To recognise which side loosens or tightens screws, you can print the bit holders in different colors. The tightening side also has the logo on P1.

There is a small hole in P2 for glueing in a 5mm magnet.

All of the parts are easily changeable!

• Please give me feedback so I can make the product better!

Printing instructions:

• Printed with few supports from PLA (Pictures where to add supports are available)
• 0.2mm layer height and 15% infill for P1, P5 and the pins
• 0.15mm layer height and 100% infill for the rest

I apologise for the assembly instructions, they are a bit complicated.

Assembly:

• The Parts that have small dots, and P1L (Cylinder) without logo belong on the same side. (To loosen screws) 
• If the mechanism doesn't work, the springs might need to be shortened. (I cut the tighter winded parts off of the springs)

1. Place P2 into P1, so the threads are inside P1
2. Place P3 into P1 and hold it in place through the hole on the side of P1 and screw P2 and P3 together. Make sure you got the parts right.
3. Place P4 into P1 with the teeth faced inwards. 
4. Place the pen spring into the hole in P4 and screw P5 in place, making sure P4 fits into P5.
5. Stick one of the pins through P1 and P5. 
6. Repeat on the opposite side. The threads are opposite on both sides.
