Sprockets for beaded cord
£6.00 Sold out
This is a pair of push-fit sprockets for driving beaded cord in a Polargraph machine. These are 3D printed in a higher-temperature polymer (T-Glase or ABS) so they don't get soft when the motor shaft heats up.
The hole has a small flat in it, that lets it engage a bit more positively with a grooved, or flatted motor shaft. The hole is a tight fit on a 5mm shaft.
