Threaded refill cap for soap dispensers

This is a remix

The original design was intended for gluing, which I didn't find particularly advantageous, so I made this one from TPU with a lip (see Blender image) so that it actually holds and does NOT need to be glued.

After printing, simply remove the supports and drill a maximum 30 mm hole into the container using a step drill bit, don't forget to deburr. Rinse the container to remove drilling debris. Remove the locking screw, insert the adapter slightly at an angle and push in the rest (possibly slightly twist in).

Have fun printing.
