I made this so that I could mount my brush cleaner onto my Skadis hobby board along with my other hobby mini painting supplies. The brush cleaner I use is this one and is designed to fit this. You will also need to print a ultimount connector which I have attached to this model.
You should be able to print this without supports with a brim (or without if you have god tier bed adhesion) but if you're having issues the easiest is to put it on the mount side with supports.
The author marked this model as their own original creation.
