This is a simple way to use a little bit of filament to keep the wrapping paper from running away. 

You will need a 1/2inch (12.7mm) dowel, broom handle, or PVC pipe for the round one holder. The rectangle one is for a yard or meter stick. Whichever one you like don't forget to print two of them. Lay them on their side and there will be no need for support filament. The are only 20mm wide. Again I was going for a simple, low filament option.

I measured these for my desk which was 18mm. I have added separate files for if your table is thicker than mine, you can alter it the table part and then add whichever piece you would want and recombine them in the slicer or throw it into your own software to change it.
