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](https://www.thingiverse.com/thing:2277141) from [arpuss](https://www.thingiverse.com/arpruss) to create the thread. Source is provided and fully parametric, so its possible to create different sized containers with threads for other dispensers.
