Check out the updated Joints+ for Version 1.0 of Dummy13.

Stronger Joints for Larger Scaled Dummy13  models. 

What did I change? I added a gap in each joint to allow for easier assembly and provide a longer-lasting grip. This is only for scaled-up versions of the Dummy13. The minimum Scale I recommend is 600% however I provided the f3d file so you can modify them if needed. They still require a lot of effort to assemble however I did not need to use any heat. All files are scaled to 100% to make sizing easy.

Printed in pla, 4 walls, 10% infill.

When assembling the hip/shoulder joints insert them at this angle to prevent cracking.
