This is a bottleholder for a kickboard. My daughter really has to get all the credit, because she designed it and i simply materialized it. It will hold a normal 1/2 plastic bottle. Print it, snap it on, take a ride and stop and have a drink whenever you need.I printed it with no support and 0.35mm layer in ABS. Print it and screw the to parts together with a 3mm screw. Its made to be mounted on the 33mm rod and has a inner diameter of 76mm. Snap it on!
