Idea trotted in my head since I knew about 3d printers!
When https://www.thingiverse.com/thing:3431217 came among I asked him to separate the paint from the pot which he did very promptly but by lack of STL I couldn't print it.
I founded more challenging to design my own under Solidworks and make it as realistic as I could than manage different file converters I wasn't that much interested in.
There you are! , 11 now, I got a few rings of orange from a adjacent lab !!
I shine them by putting 40 minutes in acetone vapour. Only works with ABS though, I don't know any easy way with PLA.
Was asked to make one with a wider base and slightly higher as for him it snapped off when printing or removing the support. This the so called wider paint"
Enjoy and post your makes.
