ECOtanka Waterbottle holder for bike

This is a easy to print bottleholder for Bikes. It fits for ECOtanka bottles with the size of 1 litre (trekka Tanka). The holder is for bikes with 35mm frame diameter. But it fits also on a bit bigger or smaller one.

This holder is super stable! Use M6 bolts for fixing the parts.

Tape some foam or felt in the holder to get this thing very silent and safe for your bottle!
