My soap-dispenser came with a pretty crappy container made of superthin and brittle plastic. The first didnt made it past two weeks, the second one gave up after a few month. After the second broke down, i finally created a decend replacement that can withstand the presure while dispensing soap foam.

This one is much stronger than the original and slightly higher. It has markings for correct filling with 60% water and 20% soap. So its worth printing with some transparent material.

I used the Yet another thread library for OpenSCAD from arpuss to create the thread.

Source is provided and fully parametric, so its possible to create different sized containers with threads for other dispensers.
