A simple and elegant towel hook for glass doors with a built in spring.

The built in spring grabs the glass so that you do not drop the hook every time you lift your towel :)

I made multiple models that fit doors from 5 to 10 mm thickness. (On request I can make other sizes)

The spring was modelled and tested with PETG and PLA material to have a nice grip and not break the spring. In the images of the simulation you can see that the stress from the deformation is lower then the typical tensile strength of PLA or PETG. meaning the spring part should never break, unless you push on the spring part trough to the outside.

Additionally I have included the model without the built in spring in case you do not like that feature.
