My Dad asked for a label dispenser for a roll of labels that is 60mm in diameter with a 25mm hole for the tube and approx 55mm wide (similar to these), so I remixed one I found on thingiverse here (https://www.thingiverse.com/thing:2361685). The main changes are a knob that screws on to secure the lid, and some indexing tabs on the inside of the lid to help keep it in place. I have to print this and if it works I will post it up to Thingiverse and Cults3D.
I plan to mount this using large 3M command strips, however it also has 4 holes for mounting using flat head screws.
The link is updated 9/20/2021 since I had to remove and re-add this due to a bug on thingiverse which keeps some things from being searchable or showing up in "my designs".
