A pegboard mounted paper towel rack.
I designed it to used these automotive ¼" push rivet fasteners:
This is a modular system. I designed both a left and a right side with a cam lever / removable arm, and also a fixed arm so you can choose the combination that works best for your application. You can use the fixed arm on either side, with a removable arm on the opposite.
Or, if you prefer you can use a removeable arm for both sides.
To swap to a new paper towel roll, simply rotate the cam lever up, remove the left holder arm, and remove the empty roll. The new roll goes on, right side first, then place the left arm into the paper towel tube first, then position it in the base rocking it downward into position, like an AK magazine.
Then lock it with by rotating the cam lever downward.
The cam lever prints with a built-in support that is part of the model. After printing, just break off the support and throw it away.
The author marked this model as their own original creation.
