In my bathroom there's nowhere to properly attach a toilet paper holder.

For some years I used this model Toilet Roll Radiator Clamp by mmeno - Thingiverse, but it had some limitations as the paper roll would often fall, and the axle was fragile. The holder finally broke after my kit put some weight on it.

I then found this Toilet Paper Holder for Heater Attachment by tripledot - Thingiverse but it didn't fit my heater. I liked it better as it was sturdier, so I modified and combined both.

In the end I attached mine “inside out”, but I like the aestetics.

The shaft is good for rolls up to 100mm long, so the model needs to be extender for longer rolls. I designed it to fit a 8mm diameter wooden dowel instead of gluing.

Rolls up to 140mm diameter work.
