O, What A Ring
These translucent silicone O-rings are 1/8" thick and measure 3-1/2" dia. Nice belts for science-project motors and even nicer for your slingshot needs. Crafters will see jewelry material that the metal-detectors won't care about.

Or gear down-for the science fair or for any number of hobby projects. This hard-to-find set of (3) combination spur/beveled gears-for when you want gears set either straight or at 90° to one another-also has one small spur gear, plus three bushings. All in red, green, or blue plastic (we'll pick). The combo-beveled gears are 1-5/8", 1-1/4" and 27/32" dia with 3/16" bores to accept the bushings, which are 3/16" OD, 3/32" ID. The straight gear is 17/32" dia with a 1/16" half-bore. All are 24 pitch.

Pull The Other One
But you’ll need a double pulley for that. Luckily, we have one right here. Double pulley, 1/2” dia with 3/16” brass sheaves inside a 1-1/16” long teardrop-shaped plated steel housing with a 3/16” hanger on top. Our Pulley Plenipotentiary says it’s perfectly capable of hoisting a good-sized plant up there to hang in your clerestory windows.

Nylon, With Teeth
You pick from our nylon gear collection. The 30-tooth gear is 1" dia, 32 pitch, with a 20-degree pressure angle. Measures 3/32" thick on the face with a 3/32" bore on that side and an 11/32" dia x 3/8" long 9-tooth shaft with the same pitch/pressure. The 32-tooth gear is 1-1/16" dia, 32 pitch and 20-degree pressure angle (so it'll mesh with the 30-tooth). Measures 3/32" thick on its face with a 1/4" bore and a 15/32" dia x  17/32" long 13-tooth shaft with the same pitch/pressure.
