Description
This is useful if you have an office chair with casters and you want it to stop rolling around for some use or other, and also don't want to swap the casters only temporarily.
You can stand a few of the casters on the blocks so that it stops rolling away. I can use only two on my chair.
By default they are designed for casters 63-65mm in diameter and 55mm wide.
They are designed to lift the caster only slightly off the floor so not to skew the chair too much (but you could use a block under each), and center it on the block. They are stackable and have a tiny channel at the bottom to grip some hot glue which helps grip the floor better (say if you have hardwood floors).
I needed this for a non-permanent flight simulator setup where I'd need to use pedals, which was impossible using a chair on casters.
I printed mine in PETG with 5 perimeters which non-scientifically seems to hold my weight and the chair's.
