Lost the clip for the parasol so I decided to make a compatible replacement. The idea was to make a sturdier clamp that would not "pop" off when re-positioning the parasol and could also be useful for attaching other things to the frame, for example cup, phone and bag holders. The clamp took a little while to design in OpenSCAD due to the "funky" semi-elliptical tube frame. Disclaimer: Obviously this clamp and parasol adapter has not gone through any rigorous testing so please use at your own risk. I don't want to be responsible for anyone getting fingers trapped or parasols falling off etc...
