This fits a 3m long tape measure.
In order to have the maximum strength in the hooks you should print the part using this orientation (organic supports, on build plate only):
![]()
I printed this in PETG with a 0.6 mm nozzle, 0.25 mm layer height, 2 walls/perimeters and 15% Grid infill.
On request I can provide versions with different dimensions or you can modify the STEP file yourself.
The author marked this model as their own original creation.
