Bead chain gear for stepper motors with 5mm shaft, e.g. for Polargraph plotter
Description
A Remix Of The Bead Gear Found Here Http://Www.Thingiverse.Com/Thing:42188 - I Only Added A Part Ready To Be Put On A 5Mm Shaft Of A Standard Stepper Motor. The Shaft Can Be Fixed With A M3 Screw From The Side. On My Printer The 5Mm Hole Was A Bit Too Tight, A Bit Of Work With A 5Mm Drill Fixed This. The M3 Makes Its Own Thread When Screwed In.
