I designed this wall-mounted paper towel holder for my workshop, but it works just as well in a kitchen, garage, or utility space.

The model is easy to print and assemble. You'll only need:

2x M4 screws

2x M4 nuts (used as the pivot axis for the arms)

A notch is included in each arm to allow adding a rubber band, in case the weight of the latch isn't enough to return the mechanism to its default position.

The default distance between the two bases is 23.5 cm, which can be adjusted to suit different towel roll sizes.
