Adjustable thumb for InMoov
by Anar, published
It gives more DOF by allowing the thumb's angle to be adjusted.
It uses the same wiring principle as for the fingers, and the knots will be hidden after gluing the tip part.
Updated 08/08/2012 : uploaded the parts for the right thumb
Updated 28/08/2012 : I made a new version of the base that is more respectful with the original InMoov's thumb angle. It's also stronger. Please read instructions.
Updated 16/11/3013 : after Balse's constructive comment (thanks!) I have corrected a few small problems. Only the right thumb is available ATM but I will also upload the left thumb soon.

Hi Balse !
I completely agree that all these derivatives are counter productive by adding ambiguity on what to print exactly.
That's why I have decided not to upload here all the corrections I make to the project and prefer to put them on my blog where Gael can come to pick them up and replace the originals part himself. This way leaving all the parts at one and same place under Hairygael's name and control.
So you're welcome to send me your correction and I will put it here with all credit you deserve.
Thanks again for helping at making InMoov even better !
I found another little issue. If you install this Thumb with the covers on the wrist, it won't turn. This is because the original thumb base is rounded on the top and the bottom (im talking about the structure on the back side of the base, where the rod goes trough). Yours is only rounded on the top side.
I took the liberty to correct this little issue. I'm currently printing a sample to test it within the assembly. If everything goes according to plan, I would like to send my corrected version to you to publish here. I think it serves the users more if they find the complete Thumb under one roof, instead of creating derivates. (And I have absolutely no problem not taking credits by publishing it under your name!!!).
What do you think Anar???

Give a Shout Out
- After removing supports, fix the 2 biggest parts together with an M3 20mm bolt as axe.
- Put 1 wire into each hole and make a knot on each
- You can now glue the last part and it will hide the knots (you can use acetone for gluing).
- take away the original thumb, remove the base part and fix it back to the new base.
- put the 4 thumb's wires in place
