Hi Angela, the inner diameter on the wheel is 6 feet 3 inches and DXF drawings can be easily scaled scaled in AutoCAD. The laser cutter guys I worked with scaled it for me to fit a plywood sheet. Scale yours down by half and your wheel diameter should be just a smidge over 3 feet. That should be big enough for a Maine Coon :)
The DXF files can be scaled to whatever size you'd like. I used AutoCad to tweak the files a bit and scaled it so that every grid line was 1 foot. 4 grid lines by 8 and you have yourself a standard sheet of plywood. The laser cutting guy used AutoCad as well and was able to read the scale that I set.
Hi PT! I don't have the DXF's anymore, only a modified DWG of the Bearing Stand Plate that has more slats added in for the wheel that would fit onto a standard 4'x8' sheet of plywood. I see Robb got you the original, would you still like my modified DWG?
Final update; did a lot of tweaking and adjusting. The wheel no longer rubs against the base and my dog is having a blast on it.
