Could you post the tooth counts of each stage and any math you've done to confirm you'll have enough power capacity with the belts.
Also need to think lot harder about that inverse pneumatic. I know this is a rough CAD but what you have could potentially kill the cylinder, way to flimsy.
Otherwise I like how it's turned out.
EDIT: by belts not lining up I think he means if you're not carful how you join the pulleys together one of the two belts might not fit into the teeth correctly.
EDIT2: pneumatic is less flimsy if you have another one the other side. Still could be stronger.

The spacing worked better to have a single large gear for the first stage. It's thinner than pulleys and I'm not concerned with the width of the gearbox.
TBH I haven't done any math for the strength of the belts. Again, I didn't intend this to be a production gearbox and more an experiment/proof of concept/CAD practice. I'll post the tooth totals though. I think it's 18-50, 18-30, and then either 20-50 or 30-40.
What about the paramedics are flimsy? I can always add a support on the back of them.
Edit: I realize that the pictures pneumatic is orientated wrong. The fittings should be either vertical up or horizontal to the outside of the gearbox.
