A tape holder for tapes size from 120mm to 80mm. Design to be wall mounted. You need two printed pieces and 2 booms (12mm or 12.8mm/half inch for you imperial guys). I've used one meter booms and they bend little bit in the middle, so its just about max for booms this size. For longer booms use at least 3 brackets.
You may need some file action since the booms are usually over sized. If the booms are to loose use some CA glue. Holes for the screws are 5.5mm, so use 5mm screws.
I've printed mine in PETG with 30% infill, but PLA will also be fine.
