I'm doing up my work space at the minute so this is just a fun little add on I made for my desk earlier, it's free to all members and I've added links to the 3mf and stl below in case anyone want's to make one for themselves. The 3mf is all one layer for the surface part so it will look a complete mess in the preview until it's sliced, but it prints fine with Aracne switched on. For the stl if you pause at layer 11 you can do a colour change for the rest of the print.
Happy printing and enjoy your morning coffee!
