The Cranked Extendable finger

Challenging print inspired by @mellowsnus comment

1. use a fine detail as possible 0.08mm
2. Print all parts separately and upright
3. Only support required is at the bottom of the hand where the cogwheel goes, manually paint the supports on it if possible
4. When printed ensure to remove the supports and smooth the surface
5. Use some lube on the thread of the cogwheel and ensure the finger rotates smoothly on the thread
6. The finger is inserted in the hole from below using the alignment rail on the finger and the grooves in the hole you may need to either sand the rail or clean out the groove, ensure that the finger moves up and own the hole smoothly but cant rotate, add some lube to that
7. Assemble and Crankup your fingering :-)
