Bicycle Exhaust

thingiverse

I was inspired by this design by Amy W: https://pinshape.com/items/23699-3d-printed-bike-motorcycle-sound-maker but ended up redesigning the whole thing to fit my kids bike. My printer only prints up to 15x15x15cm, so that's why the pipe is in three parts. I incorporated parts from the following designs: - NUT JOB: thingiverse.com/thing:193647 for the nut and bolt - Hollow Cylinder: thingiverse.com/thing:2210027 for the screw thread - Box with sliding top: https://www.thingiverse.com/thing:201304 to attach the pipe to the bracket I designed the bracket myself from different ideas and the pipe was mostly mine design apart from mashing the other parts together. The only bit missing (apart from a bike) is the bit that makes a noise. I used an old raft or two together held in place with the bolt make it just enough to touch the spokes otherwise they break really quick.
