About this model

This gravity hook is the towel hanger I reach for when I want a grip that works without any springs or latches. The weight of the towel itself makes it clamp, so it holds firm without tearing or pinching the fabric, and the two parts just snap together.

I prototyped this design more than 10 times, and it has held up for daily use in bathrooms, kitchens, garages, and outdoors. The two ready-made screw holes make it easy to mount, and the pattern on the face can be changed in the slicer, which is the part I like best.

Tips

• Heavy towels: it is meant for hand towels and lighter ones, not heavy towels. If you do use a heavier towel, curve the top of the towel so that when it is released it sits on the marble and does not slip.
• No XY change: this is not a passthrough model, so I left the XY settings as they are.

Customization

Customization tutorial for patterns, if you do not use one of the provided profiles. Step 1: Import the file to your slicer. Step 2: Place it on the face, flat on the build plate, as shown in the tutorial photo. Step 3: Right-click and add a Height Range Modifier, set from 0 to 7.75 for the best results. Step 4: Click Range in the sidebar, and turn top and bottom shell layers to 0. Step 5: Go to infill and infill pattern, choose the pattern and the percentage of infill you want, I recommend honeycomb or triangles at 25%-40%, then enable supports (tree auto) for the best results.

Reminder: the customizable pattern is only visible when you slice the blank patterned design profile or follow the tutorial above.
