Bicycle water bottle cage with zip-tie attachment

This is a water bottle holder designed to be zip-tied to a bicycle that doesn't have bottle cage screws (or for where you want to attach it to a tube without screws).

I recommend ABS.

It prints in three parts which need to be glued together. (It is not essential that the bond be super-strong.) I used ABS juice.

I also cut out a bit of inner tube and hot-glued it on the base of the strap piece to keep things even more stably attached to the bike.

No supports needed.
