SBA3 Shape Maintainer
thingiverse
I printed the original designed by IMWAYTOOTALL, but it was too loose. I don't know if there was a revision somewhere along the way that changed the brace or what the deal was, but this one fits what I have. I revised the insert area to make it bigger and change the profile a bit, and changed the angle where the base meets the back of the brace to fit a little tighter.
