Thanks for your good words guys So I peped the Codpiece and the right Thigh. I peped the codpiece without an Issue.
The length of thigh is to long but the diameter is zu small.
I have to increase the file with paper to get the right size. On the first picture you can see I increased the thigh outside. Next time i will increase the tigh inside to have a
better look. We will see how is the result next time
