This was a fun experiment mixing PETG and TPU for a print-in-place jack (when you add an M6x130mm bolt and rivet nut). It's probably not safe to be storing this much tension & energy in an 80g 3D printed part, but the fact it didn't even fail at 400lbs kinda blew me away.
Made a video about this "flexijack" that shows a few other rigid+flex ideas I had, and also talks about some of the creative modeling & slicing techniques I used to make it:
I haven't seen much about this topic (hybrid rigid+flex prints), let me know if this inspires any other ideas. I'd like to try more things with the concept. #technology
