Chair Stopper

Description

So you want to race and have a chair with wheels beneath you?
No problem this fixes your issues with rolling back when you brake. Just print two or three of these and you are set for your next race. It doesn't matter whether you have a carpet or any other type of floor beneath you. The Stoppers are designed so that they can grip onto any type of floor. You just have to put some small rubber feet underneath them and they grip on a slippery floor. 

Printing

I printed them on an Ender 3V2. I used PETG and a 0.28mm layer height.
