This adapter made of TPU is for mounting bicycle accessories, such as bicycle computers or lamps, on children's bicycle handlebars with a small tube diameter.
I've attached the Fusion360 file so you can resize as needed. The parameters can be easily changed.
The story behind it is, my little daughter wanted to have her own bike computer on her Woom2 bike. Since I had an old one lying around I just needed an adapter as the small bikes have such thin handlebars that normal bike accessories won't fit.
The basic dimensions of the STL, 3MF or GCODE file are (changeable in Fusion360):
happy printing and please post a make, i would really appreciate it :)
