How precise is this? I'm always looking for ways to reduce cost, and this looks like a good one, but it seems like play could be a problem.

One of the harder things to find is the offset axis spacer, the thingy that is intended to tension the third wheel against the rails. Could you make that too?

Needs some design for the plate, but with some tweak and a good spring loader it may be possible !

Very cool PropsFactory! Nice job on these. Thank you for sharing.

any video of this in action? Looks great!

Soon, testing with a 30cm line, and maybe a tensioner.
