Print in Place Collapsible Rice Hat V1

A print in place collapsible rice hat. When the top point is rotated such that it pushes the pieces together then internal cams will engage and keep each piece within a certain angle of rotation. The string and how you attach it is on you. Just keep in mind that this hat is designed to shed water and some methods of fastening a chin string may compromise that feature.

This one is a tough print. It's a torture test that isn't for the faint of heart. I'm confident that a well-tuned and calibrated printer with a quality material should be able to do this just fine. The part that makes this print more difficult than most is the thin pieces and the printer having to go between all of them without hitting one as the print get taller.

My most successful print was with PETG and a 5 layer and 4 mm expanded raft (to help with bed adhesion) but for some reason the edges got really fuzzy about 60% through and started making contact with the nozzle, which ultimately lead to a layer shift. It's possible that my PETG just got waterlogged from humid air before the print could finish (I did dry it but I probably should have it print out of a drier next time). I printed this on my Prusa MK4 and it takes up the majority of the print area - it will not fit on small print beds. I printed with a 0.6 mm nozzle. If you have any suggestions on what I could do to successfully print this guy please let me know; I'm open to changing the model if needed.
