Pinching Gear Towel Holder/Rack/Hook

Most methods of hanging towels are boring! This one isn't.
Fully printed. No fasteners required.

Print conditions: 

• PLA or PETG (other materials have not been tested)

• Supports required on the inner axle track of the body. Included 3MF enables this for you. 

• 0.2 mm layer height in Structural mode (not speed)

• Axle should be printed with 100% infill to increase the weight (the 3MF file does this for you). The pinion/axle combo needs to be heavy in order to fall to the lowest point in the track in order to be ready to mount the towel again.

• Print the models in the default orientation as downloaded

Assembly Instructions:

1. Insert the pinion gear with the teeth properly aligned to the body

2. Hold the pinion gear in the center of the axle track

3. On the body, spread apart the axle track and insert the axle through the track and into the pinion gear. Make sure both pegs on the axle are locked in by the axle track on both sides.

4. Adhere it to your surface of choice in the correct orientation as shown in the photos. Double sided foam tape, command strips, or the painter's tape with super glue trick* (explained below) works well. 

I am considering designing a model that is compatible with screws. Let me know if you want this.

*The painter's tape and super glue trick: Put painter's tape on both surfaces. The wall and the towel holder. spread a thin layer of super glue on one of the taped surfaces. Press them together. This method works best on smooth surfaces.
