I have all 3 models going on 3 different printers. All coming out very nice. The video helped get the first one together, the other two just take some thought to follow the same concept and look at the parts to see where they go. Printed in ABS, PETG and PLA so far. PLA almost done, anxious to see how it holds up.
Spitballing' here, can you embed a some sort of a pattern (like maybe zebra stripes, tiger stripes or a nice wavy Stars and Stripes) in the outer parts so it could be printed on 2 or 3 color printers? I think that would add nice touch to them, too.
Hope you come up with some more clever designs!
