doona liki trike bell adapter

i ordered this bell from aliexpress: https://a.aliexpress.com/_oFu8ror and wanted to put it on my kid trike. it came with rubber band which my boy ruined in a minute (7 months) so i printed this strong adapter. i designed it with the nut fixed inside the model so you have to pause the printing. the rotating part is print-in-place. glued them together and it works great.

printed in petg with higher infill to survive the sun outside and the strong kid.
