Just noticed from the first pic in this thread that you have Hatchbox filament. Good choice, I built my whole bot out of Hatchbox.

Yep I really like that brand. I have had very good luck with it. Only issue is it is getting hard to get sometimes on Amazon with the supply chain delays.  I am waiting now on more black PETG to arrive.

Merne: Have you tried "Rust-Oleum Ultra Cover Spray can's? Also try painter's blue tape. That's what I used, but I spray a light cost first then spray it again.

Shawn: That is actually exactly what I used and had issues with. But I need to move forward and see what happens

Well I went out and purchased some new painters tape and did a test with "Rust-Oleum Ultra Cover Spray" starting with very very light dustings for the first three or four coats letting it dry for an hour between coats. Then I painted a covering coat let it dry and removed the tape and it was perfect so I decided I would tape up one thigh and gave it a try and it worked great!  So I did the second one the same way and once again it worked with no bleeding.

Sorry about the lighting in the pictures.  I have very bright LED lights in the garage that causes glare and shadows that can make things look worse then they really are...

Nice job. Gael really did a good color combination with black and white. Just seems to work.

Well I have come up with the final version of the shoulder joint seen below.  90 degree rotation looks to be about 4 seconds and 120 degrees in about 7.5 seconds based on videos I have seen of the standard Inmoov joint this looks like it is running faster.  I have ordered a 180 to 270 converter to increase the range.  It sucks when to buy a servo they say moves 180 and it only really travels 120 degrees.
