Ah okay. I’ve never come across anything like that before. So don’t think ezrobot will be able to help.

You’d think something like that already exists out there as a kit. Wonder if anyone here has seen that? A mechano type kit that worked with servos would be super awesome. Never come across it before but maybe it does exist hmm

That's alright, thank you for your help. Hopefully I find something.

There's always the winch style gears from servo City but they are pricy: https://www.servocity.com/servo-gearboxes/

Otherwise, I'd suggest checking out the inMoov project, the shoulder section has a high torque, servo-driven,  3D printable worm gear.

Alternatively, you could TinkerCAD to design and 3D print gears that are mountable on common servo horns, which shouldn't be too difficult.

*Edit: Yet another solution could be to laser cut acrylic or Delrin gears that mount on servo horns. There are 2D gear generator programs out there that can make this quite easy. I have a laser cutter if you need some assistance, but I'm unsure how far away from each other we are. *Lol, looks like we are a world away Australia is a bit far

Thanks so much, that's a great idea of attaching to servo horns already. Which programs can make these 2D gears? I'm not sure if I'll need it due to the first suggestion being so achievable but thank you very much for the offer.

Here's one that exports to SVG: Gear Generator

Sweet, thank you very much.

Thank you for your help
