Handgripper

This Design of a mechanical Hand Gripper is a simple Tool to keep your Hands clean in many Situations.
It can be used to grab small Things, open and close Doors, push Buttons, or just to pick your Nose.
When it is not needed it can hang on your Trousers with it's included Hook, ready for Action.

All needed Parts can be printed. There is an Option to use the Spring of a Ballpoint Pen, to get a normaly-closed Gripper, that can hold small Parts even if you cannot hold anything anymore.

You will need:

1 x Unterschale
1 x Oberschale
1 x Zahnrad
1 x Zahnstange
1 x Abzug
2 x Greiferfinger
4 x Strebe
1 x StiftClip
8 x Stift6
1 x Stift8

Printing the 3 Stift Versions is working best for me using a Brim.
Depending on your Printers Settings you may have to Drill the Holes with a 6mm and a 8mm Drill.
Make sure that every Part in the Assembly can move without any Force.
