In the slim chance any would ever need this. Got annoyed with those rubber holders that come with the fan and strap to your handlebar and made this.

Holder for remote(s) for probably the best indoor training fan there is, Vacmaster Cardio54. Clips into Wahoo KICKR Indoor Cycling Desk.

Two versions for the holder and the clip. One or two remotes, and clips for thinner and thicker parts of the slot. Model would be quite tricky to print, suggest to print the parts you need and glue those together with superglue.

3 walls is enough to make all parts solid with 0.20mm.
