Body Glove Boogie Board Strap Bracket for back

My cousin lost the original part. Fusion unfortunately does not have the right thread and I am lazy so the thread does not fit too tight. However this is does not matter when you tighten it properly as it ends up working alright. I printed in PETG with 100% infill and it is not causing any problems for me. 25% infill is probably also strong enough, I just wanted to stay on the cautious side. If there is enough interest I may model the other part of it that attaches to the strap.

Recommended profile:

PETG, ABS/ASA, CF materials.

0.2m layer height

25% - 100% infill - more the stronger

4 walls, 5 top + bottom
