After a lot of use the strap on my 3m 7503 became very brittle and snapped. perhaps due to exposure to solvents and paints. I looked online for a 3d printed replacement to save a buck and found one, but it relied on glue to hold it in place. This remixed version instead forgoes clips to use a simple series of holes to thread the strap through to keep it fixed. This also makes it adjustable.
I was originally going to print with PP filament but CA glue didn't hold the 2 parts together as well, so I printed in PETG instead and it looks okay. ABS and some hobby cement would probably be my first choice but I did not have any on hand. You could probably avoid gluing the 2 parts together altogether if you loop the straps in firmly.
The model is not very clean as it was thrown together extremely quickly.
