Why are gears so expensive?
I don’t want to pay $15 for a gear

>>2937722 (OP)
Gears are machined, with big machines. Big machine is big expensive. You can 3D print a shitty plastic gear for $0.1 but it's gonna be shitty and +tic.

yes but it might accomplish its desired task. picel cut three .75 lead mm threads without failure and put 5 bill$ in my pocket by doing so

im not sorry for phonefagging

That's cool and all but it's probably going to fail in about 1000 times less time than it takes for one of the metal gears to fail.

>>2937733
you missed the point where it did exactly what it needed to do
in fact its service life duration appeared to be many orders of magnitude longer the needed for intermittent use

I pay literally less than 2€ for a module 1 12 tooth cog. For the amount of work in it thats crazy cheap.
That being said they are bad. Literal trash if yiu run them on the meter. Doesn't matter tho, just dont design shit.

Can gear be made to a universal and generic sizes, like how everything else is standardized?

What standard are they following?

There's just common modules that are being produced and that's about it.
