Quick Release Version of Gimbal Cup Holder

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5326473.

I have added "slide on" holders on my son's stroller to facilitate sliding things on and off, so I remixed the design of the slide on bracket + the design of the gimbal cup holder (from https://www.prusaprinters.org/prints/129329-universal-travel-coffee-gimbal) to create one design, allowing you to easily and quickly remove the cupholder in a modular fashion.
