Ngàm giữ bình nước cho xe đạp gấp (Flex TPU)

Rigid printed holders were giving me fear of breaking on the road at high speed, and a lot of them were designed for some kind of screw mount that I guess bigger bikes typically(?) have but that's definitely absent on a small folding bike. I suddenly just thought up this one: flexible, tightly hugging the frame, secured with a row of zip ties at the bottom where they're not very noticeable unless you look for them specifically.

Made for a 70mm diameter bottle, unfortunately mine ended up rather tight so I recommend using hole expansion in the slicer by just a little bit. Also definitely use big mouse ears or a brim to hold the thin halves that hug the frame to the print bed, they WILL detach otherwise (mine printed all the way with them detached, just with some ugly blobs, in the literally never visible part so I left it lol).

Designed specifically based on the measurements of the Aurorita Folding Classic 20, a modern folding bike from Argentina. I think the shape of this type of bike is similar enough everywhere though..

Modeling this was quite a PITA in FreeCAD, specifically making the holes for the zip ties follow the curve in the correct way xD
