I need 4 of these manufactured and if the completed project is acceptable I plan to order more. The wheel height should be around [url removed, login to view] inches. The idea is that these could slip on to a normal chairs leg to make it into a Rollable chair. I will message the producer I choose on the dimensions for the rubber piece on top. The rotating mount needs to rotate 360 degrees and doesn't necessarily have to be the same design as the one I posted in the pictures. If you have a better design please message.
