Water bottle holder clamp for bicycles

thingiverse

One of our bikes didnt have stubs where you can mount a water bottle. Printed these clamps out to clamp to a 38.5mm down tube - along with a 1mm rubber strip (made out of old bicycle tire interior bladder). Fits the standard M5 hex head cap screw, and M5 nut. When time to fit, just put the left and right side over the down tube, then slide fit into each other. Modelled in Fusion 360, so I've included the f3d file if you need to make edits. Just 1 support needed, for the slot. Provided 1 STL for both left and right sides, and another 2 STL files if you want to print separately. Tried doing 1 print for both sides at once, but found it difficult to separate as I was using a brim.
