robot hand: print in place & tightenable

more recent version: https://www.printables.com/model/1083785-robot-hand-v2

A robot hand: print in place, but posable via the embedded tightening screws.
Slice with standard Cura PLA 0.2 mm layer / 0.4 mm noozle. No brim, No support (there are built in supports where needed). It fits on a small printer like my Artillery Genius.

First try to print the test double-09 joint (25 min). Remove the built-in support below the junction.
Check the screw can be unscrewed to unstuck it, then screw it down, with a small screwdriver.
If everything is stuck,try to reduce flow extrusion on your printer (i have to set the flow between 95% and 90% on my printer, depending on the filament).

Then print the hand (main-7.2, 9h00). It should print and come out of the bed without problems.
There are a couple built-in supports to remove on the thumb joints (easily).
Unscrew to unstuck, then screw to tighten the joints as you like. Make sure to push the screwdriver deep in the screw slit to properly drag it the first time. I had to make the slit rather thin to make the screw more robust. Be careful, dont hurt yourself! After these first turns, the slit will widen itself a little and it will be easy to engage the screwdriver.

If you have any questions, let me know in the comments. I’ll be grateful if you like and post your makes.
I would love to read your comments or to see how your makes look like!

 PLEASE PLEASE PLEASE tell me how it printed for you? I took great care to make the printing reliable and the object robust, but is it really the case? Give me some feedback! Thank you.
