I really loved the original model by cashkotulka and want to give them a lot of credit. It's a very cool model for a third post. They did a lot of work that seems be meant to make it print without supports.

I did some fixes on one arm and scaled it up 170%

I have updated this model with an M5 version that separated the thighs and lowered the bones to the print bed.

I made an M6 version where I changed the forearm and reduced the mesh complexity.

If you're having trouble with the anything becoming detached add a helper disk to that spot.
