Recreated son176 idea and cleaned it up a little.
I scaled the X-axis to 220 mm and used 5% infill, and it turned out great. It took three days to print in PETG and had over 700 tool changes with an MK3S using the MMU3. I added sand midway to give it weight, but it ended up making a mess (I don't recommend using sand). I wanted to use epoxy resin to add weight to the base, but I didn't have any on hand; resin would definitely be a better option. If you didn't pause it during printing and you feel it needs weight, then you could also drill a small hole in the back and fill it with resin using a syringe, as the 5% gyroid infill will cause the resin to settle at the bottom of the model. I did put three holes in the bottom for those who want to make their own base to help it be more stable, but mine felt stable enough, so I didn't bother designing a stand.
The author remixed this model.
Took original design by Riolito Paildelan and recreated son176 idea to print better and cleaned up the lower side a little in fusion 360.
