GT Omega Office Chair Wheel Lock

I didn't want to spend £40 buying the GT Omega chair link so designed these to fit. It bolts to the ends of the GT Omega Classic wheel stand using the holes meant for the Classic Rear Seat Frame.

It may fit other GT Omega stands that are compatible with the Classic Rear Seat Frame.

My office chair is pictured, if you want to mod it to fit yours feel free. 

The profile has supports and 3 walls and printed at .28mm. It prints in about 3 hours on the A1. I have been pressing quite hard on the brake and they seem quite robust with these settings.
