Geoff's GT2 Timing Belt pulley Mk2 - fully 3D printed
thingiverse
Upgrade to my earlier "Geoff's GT2 Timing Belt pulley", this version does not use a grub screw which marks the 5/6/7mm rod, making it much easier to slide the pulley OFF the rod for maintenance. I've also changed the teeth shape to more closely match a GT2 belt, as you can see in the (partial) red pulley & GT2 belt pic The only assembly needed is to push a 3mm screw&nut into each hole - the length varies with Diameter, approx 18-22mm. You may need to drill out the center, depends on your 3D printer calibration setup. Included are 16T, 18T, 20 and 22T pulleys, each size with 5/6//7/8mm centers (except where the walls are too thin) - PM me if you need other sizes
