There are tons of plastic gears inside of printers, copiers and the like, and they are actually worth money.
A quick
Ebay search revealed that plastic gears sell for $0.05 - $0.06 each if sold in lots of 50 or more ( 1 listing had over 1,000 sold lots - another one over 500 - many have over 75 sold lots ) !!!
Looking at the listings, certain gears can sell for even more ! Stepper gears are going for over $0.20 each if sold in lots !
Heck, even plastic "pulleys" are selling !
If you had the time, it would be possible to put together "plastic parts kits" that
go for over $20 each
