eureka smillers29 but is reddy .xD . congrats .

Congrats! There is a Kardashian.stl file that takes 5 spools of plastic to print.

Good one Perry!!!

Well I have been working on a new shoulder drive and I am getting very close to having something that just may work.  I am still working out the servo pot setup but I think I may be able to make things work...  fingers crossed anyways.   Here is what I have so far...  Doing this stuff in Tinkercad has been challenging to say the least...  I need to really learn a CAD program!

It should have 3 times the torque of the JX servo PDI-HV2060MG 62KG Metal Gear High Torque servo I think the speed of movement should also be an improvement but time will tell.

hi smiller29

that looks very promising . am going to change my inmoov to . using gears in waist and shoulders insteadt of taking the pot out . did you ever use flex filament ?

To answer your question no I have not.

This gear will be the outer most rotating part the teeth on the outside of it I am planning on having a spear gear connected to the pot. I also will be adding 4 holes in the below gear to connect it to the rest of the arm.

If I am understanding your design you are adding a planetary set off a servo. Is it a 4:1 reduction? If so you will increase the torque by 4 and reduce the speed by a factor of 4. That will yield a very slow arm if I am following your design intent correctly.

Do you know what the ratio is on the Inmoov arms by any chance?
