A sturdy paper towel holder for mounting under a desk, workbench, or cabinet. This is a remix of cmerkle's design (https://www.printables.com/@cmerkle_367095) modified to use M3 nuts and bolts for mounting instead of command strips / double-sided tape. I made this change because I desired a more permanent mounting solution for my use case.
The paper towel roll is held in place by threaded knobs on either end. I printed this in PETG-GF for extra durability and chemical resistance, but any rigid filament will work just fine.
You'll need to print one of each bracket (left and right) and two knobs.
I have included the STEP files as well (I used AnyConv.com for the conversion from the original STLs) if desired. I included the models with and without the modifications for M3 hardware as well as the knob (which isn't modified in any way).
Hardware required: M3 nuts and bolts for mounting (length depends on your surface thickness).
The author remixed this model.
A simple remix in which I added four M3-sized bolt holes and slots for press-fit M3 nuts into each bracket to better suit my mounting needs for this paper towel roll holder.
