After getting my new Fastfold golf trolley I found that there were five mounting locations on it but not that many accessories sold for it.

Designed this basic quick attach keyhole ring mount to fit the trolley, and be able to hang different things needed on the course.

Small print, use 100% infill or set walls high so that it covers the model for other top/bottom surface finish.

If someone find this useful but have other ideas please remix or use the files as you want.
