Office chair wheel guards for cables and pets

Tired of running over cables, morning robe belts, and maybe even the tail of your beloved pet with your office chair? Then this print is for you!

I tried many different design approaches, but in the end, simplicity proved superior to all other designs. 
The guards should fit most office chair wheels, and the size can be adjusted in bambu studio for the wheels that don't fit. 

I also added some "ball bearings" to the design to minimize friction with the floor.
