I love my CoreOne, but it's a big block and hard to move. Luckily, that's easy to change thanks to my office chair wheel adapter :)

Remove the original rubber feet and screw my bracket in place using slightly longer M3 screws. Now you can slide the wheels into the hole.

I used those 10mm office chair's wheels. They roll really smoothly.

Print settings:

I've printed mine with PLA with 4 perimeters and 25% infill and it is strong enough. PETG would be even better. You can add supports to make the slopes print better.

Happy printing and roooolling :)
