A very sturdy paper towel holder for mounting under a desk/workbench/cabinet. I tried printing other various paper towel holders from Printables before and they all seemed flimsy or didn't fit together right, so I decided to design my own.
The paper towel roll is held in place by threaded knobs on either end. The brackets are designed to mount to the bottom of the desk/workbench/cabinet using command strips or double sided tape, since I did not want to drill holes in my new desk. I used 2x command strips per side, and it feels very sturdy.
You must print one of each bracket (left and right) and two knobs. I used coextruded silk PLA, but any rigid filament should work.
