Didn't see the need for mmu print with Printinghappy's version so I split the model to save time and material. from 11hr mmu to 7hr combined between the two prints. Originally I intended attaching the back section on afterwards. Turned out I didn't need to as it fit well enough without it.
Made with prusament galaxy silver and amz3d black at .2mm layer height.
-Split version .3mf included (silver),
You can discard the back(thin) section in slicer if you want.
-Original stl from printinghappy (black). Make sure to flip over 180° onto build plate for the same finish on front surfaces.
The author remixed this model.
