After years of use, the arm on my toilet paper holder, from Target, broke off at the pivot point.
Instead of buying a new one, I just got measurements from the original piece and fabricated a replacement arm.
Overall, this arm is 171mm long x 30mm wide x 30mm tall.
At 0.2mm layer height (plus tree supports), this is only about 18g of basic PLA.
(Use something stronger than PLA, as it does have to bear some static weight and PLA ends up stretching. I used PLA for proof of concept/testing.)
Infill: cubic at 30% infill density.
The author marked this model as their own original creation.
