This is yet another towel holder. I wanted one for some time as I was done with
using these crocodile adapters and hooks from the 80th. :D

I searched a little to find some matching idea, which would work for me, but
sadly there wasn't a single one. The available models where too big or simply
clip together types. The latter are odd, as towels are in touch with water and
the inside of these little boxes over time gets an bacteria growing place. The
given models were click in and the mechanism would break over time due to wear
off when opening them to clean the inside.

So I used the need and turned it into yet another small FreeCAD session to learn
more about CAD. It turned out well and worked first try. :)

Printing

Printing is straight forward. There is no support required as the part was
designed with build in supports where needed. In fact only the small ring
overhang on the cover part would need support anyway. Print the files as they
are and you are fine. 0.2mm layer height is fine.

The gripper ring needs to be printed in TPU. Infill should not matter.
I used three outside walls, so the object is more or less 100% anyway.

Assembly

This thingy contains three parts. The base can be screwed to a surface or be
taped on, using some good quality double side tape on the back.

The gripper object needs to be printed in TPU. It gets sandwiched to the base using the cover, which gets screwed onto the base. The flat side of the TPU ring faces towards the back (base).

That is all. Push a towel into the opening and it will stick. I made it for my
kitchen, so size and flex of the TPU is more than enough to hold wet towels.

Modification

If you need a bigger or otherwise different version, just load the included source file into FreeCAD and double click the spreadsheet. I marked the key diameter and height of the box. Changing other stuff should not be necessary. After that you need to export all
three files and done.
