Is there any alternative to this? I've attached a picture of the current design.
I've considered polycord, but the joining kit costs $1200 here and we don't want to spend that much.

Friction rollers could be a poor man's geartrain (the slippage could even be an asset). There's always chain too (maybe
plastic chain, because it's a bit easier to deal with than metal in small sizes).
Vex parts, if available, offer a lot of options as well.
If you want to weld polycord, though, you can do it with an open flame, or a hot plate and some ingenuity. The kit is fine, but not necessary for most small jobs.
See here for more ideas.
