My first design had many faults (https://www.thingiverse.com/thing:2493079).
I have redesigned most of the item and added a mount that holds the caddy on the golf cart windshield frame without clamps or fasteners. It should fit most golf carts. I designed the mount to be removable in the event I need to add a new type of mount. I might add a mount that fits in the cup holder of a golf cart.
I set the infill to 100% and used ABS. The 1st version snapped and broke too easily.
I'll try to upload photo's next time I go to the golf course.
If you do print this please let me know any good/bad issues. I've only been printing and designing for about a month.
