This is designed to printed in TPU with NO supports. Everything is bridges.if ur bridges droop a little u can clean it up with some clippers.
If you shoot in superview the very corners of the video will be blocked.
P.S. I have not tried it on the chameleon ti, so sorry if it doesn't work, but from what i understand the parts are identical.
If the first layer or two of your bridges droop you can just clean it up with some clippers.
