Printed with 0.2mm layer height. Rotate so that it lays flat on the bed, support required for hole.

Remove strap from bike light and attach to mount. Use a cable tie (zip tie) to attach it to the handlebars. 

Update 25/01/25: Made the holder a bit thicker as it was starting to fail. Also added fuzzy skin to the .3mf to help it grip the handlebars.
