This holds a 70mm diameter drinking bottle on the outside of your cage. The bottle holder is mounted to the cage with the help of a plate that goes to the inside of the cage. The bottle holder and the plate are squeezed in place with a 3d-printed bolt, with cage bars in between.
No parts are necessary other than the printed parts.
Bottle holder on the outside of the cage, plate on the inside. Stick the 3d-printed bolt through the hole in the plate and into the hole on the back side of the bottle holder, then screw it in clockwise.
If the bars of your cage are very thin (less than 1,5mm diameter), you might have to cut the bolt a little at the tip.
The model is printable without supports. I designed it for my ageing CR-10S with a .6mm nozzle and .4mm layer height, which means that it should print just fine on any printer with more standard .4mm nozzle and .2mm layer height as well.
For material I used PLA.
The author marked this model as their own original creation.
