You could make them.
Just print out a full-size template, paste it onto some 1" thick lexan (or plywood). Then use a bandsaw to carefully "nibble cut" out the shape. You could then throw it on a lathe to make sure they are perfectly round. Attach some timing belt for traction, and *bam* instant custom step-climbing wheel.
Note: this is obviously a MUCH simplified method of manufacture. If you really want to be cool you could do something MUCH more fancy (or use a fancier material).
