Ikea markus castor delete.

I sim race a lot and the wheels on my ikea markus would roll me away when i use the pedals. So i got rid of the castors and printed these little feet to replace them. You do require chair grips from the hardware store to protect your floor, but you might be able to print them from some hard TPU, maybe 95A

I have been using these for the past 2 years on fake hardwood flooring and they havent messed up the floor and are still holding up great. 

The design can be improved, currently i need to use a bit of hot glue to keep them in place, but as long as youre sitting on it, you may not need the glue. 

**If you are interested in this model, please leave a comment, i can remake it in a day as my skills in cad have improved a lot since i made this :)
