This is a mount to fix a hands-free soap dispenser to the wall.
It is in two parts: The main body (which holds the soap dispenser and provides a drip catcher) and the mount. Magnets are inserted into each to hold the device in place.
The wall mount mounts to the wall and the main body just holds to it. It can then be removed for cleaning and maintenance.
It needs 4 of 10mmx3mm magnets which need to be held in place with epoxy. Obviously these must be arranged N-S across the two parts.
There are plenty of the same soap dispenser on Amazon and elsewhere which all seem to use the same design so I imagine you'll easily find one to fit.
This is just one which I found in a quick search.
Print in ABS or PETG to be dishwasher proof.
0.2mm gives a fairly good finish.
The body prints rear down and will need support in the mounting cut-out. The mount also prints rear down but needs no support.
I am very much an enthusiastic amateur when it comes to designing. My designs tend to have two things in common
1) They serve a purpose. I like to design functional objects which have a real-world use. 3D printing for art is fine, but it's its real-world application which will take the technology forward
2) Wherever possible I design to be easy to print and try to eschew supports or complex printing; modifying the design where necessary and possible to achieve this.
