Thanks for creating and uploading the models for the paper holder. Looks good. I'd intended on designing one, but then my printer grew progressively less functional and so all 3D design and printing has ground to a halt.

This gives me yet another reason to pull the trigger on the new printer I've been eyeballing...

No problem!  It was a good FreeCAD learning project for me.

FWIW, I was able to print it on an Ender 3 V3 KE with normal PLA and at .2mm resolution without any tolerance issues. You do need to print supports for the version with plastic dowels, but they're tiny.
