I wanted a bottle cage that could hold relatively tall bottles securely, be relatively lightweight, and be easy to print (ie. without a lot of steep overhangs). I took inspiration from this design, which I liked but was too short and difficult to print without supports (but works well for shorter bottles!).
The cage is designed to hold standard 73mm outer diameter bottles, but I also designed it to work well with my bottle cage storage container. The ‘depth’ of the holder is 125mm (~5"), which I felt was ideal for taller, 24oz (~700mL) sport bottles.
There are 4 versions:
The multi-piece version separates the ring part of the cage from the end stopper, and requires drilling through some sacrificial bridges to fit a M3x20 screw and locknut. The single-piece variant doesn't need this but requires supports for the protruding end stopper.
The loose grip version has narrower walls and doesn't grip as tightly as the wider walled firm grip. The firm grip version was a result of experimenting with different materials, where the loose grip felt sufficient with PLA but not ABS, so a firmer version was developed for ABS. Using the firm grip with PLA will produce quite a tight gripping cage.
The author marked this model as their own original creation.
