Universal Office Chair Wheel Stopper (IKEA MARKUS)

Universal 3D-printed wheel stoppers that keep office chairs firmly in place. Designed for the IKEA Markus but compatible with most standard chair wheels. 

Created with sim racing in mind (especially heavy braking), but useful in many setups. To protect your chair wheels and avoid scratches, I recommend adding a felt coating (as shown in the photos).
