Been working on a home gym and came up with this option for an resistance/exercise band wall mount.
New model has smoother edges to hopefully reduce cutting of the resistance bands and your fingers. In my testing the model can take a lot of stress. Have not broken one yet. Will try soon.

Model prints well in PETG, been using many prints for a few years now with no major issues yet. But I would check your prints for sharp edges and sand them down. A few of the early prints I tested had sharpedgs, and this has damaged a few of my elastic bands. Or I just wore out the cheap bands I was using. Hard to say, but thought I would mention it.
Printing:
Important: Place model on its side. With the logo and word mark facing up.slicer: Prusa Slicer
Resolution: 0.20mm
Raft: 3 layers to protect the side fillets.
Vertical shells: 3
Top and bottom shells: 5 and 4
Infill: 25 to 50 %
Infill pattern: Gyroid
Printer: Prusa MK3
Material: PETG or PLA. Both are remarkably strong with the Gyroid infill.
Print times: 25% infill around 2 hours and 40 mins ish. 50% infill over 4 hours ish.
The Gyroid infill pattern makes the part quite strong and does not add much to the overall print times. But USE THE MOUNTS AT YOUR OWN risk. So far in my testing they have never broken but their strength depends on so many factors you will have to be the judge.
The design has the screws, make the part stronger in the axis you are loading it so it should be very strong in theory.
I mounted them to a stud with some 3 inch deck screws I had around the house. The wholes should fit any fastener under ¼ inch (7mm) with a head less then ½ inch (14mm) .
Recommended Fasteners (not fully tested yet)
3 1/4" long, screws with a head size of 5/16" and a shaft thickness is 1/4
Test the mount before pulling too hard on it!
Please comment if you have ideas for making the mount stronger or any other improvements.
Happy exercising
