Office Chair Chock for Sim Racing

I designed these wheel chocks after trying to use racing sims with a wheeled office chair, this proved problematic as the chair would move when putting pressure on the pedals. 

I designed these chocks to fit standard 50mm wheels. They use a centre “divider” in order that the wheel does not slip off during use. These chocks work well however can be improved by gluing rubber/foam to the bottom, I personally used some cut-offs from an old bike inner tube which works very well.

After printing these chocks I no longer had the problem of the chair slipping around.

You could print one chock for every wheel however this is unnecessary and 2 will suffice.

It is important that the infill is at least 50%, this is to give it the strength needed.
