Remake from this project. As the name suggests the design has been mirrored and the height extended. Also, I added some lettering on the sides to mark the functions. I have been using this soap dispenser for over a year now and I think it is really convenient.
Technical
When printing I suggest using a material which doesn't react with water (I suggest CPE or PC). THERE IS NO NEED FOR SUPPORT (incorporated in the design).
The soap pump is re-used from an "Albert Heijn" product (Image included), other pumps might work as well. If not, both the STEP and SLDPRT file are included
