Cool. I expect it'll work well enough, provided the prints are nice and smooth – which sometimes gets easier with a little break-in use, from what I've seen. You'd probably only have to print one or two extra pieces to try both ways, if you wanted to be conservative.

If it is smooth, a longer 3-wheel/5-gear (or 2-wheel/5-gear) assembly might look nice, to keep the balance.

Wish I could test it myself, but I'm not printing yet. My experience is in design, CNC and traditional building.
