Updated Rostock Carriage for different pulley size (40, 20, 16 teeths)
thingiverse
I am constructing a Rostock 3D printer and seek smaller pulleys to attain higher definition. Smaller pulleys reduce speed but should enhance quality. Instructions I created this Carriage model based on Johann's (http://www.thingiverse.com/thing:21004/#instructions) original, yet added customizable features. You can download the SCAD file and tailor your own pulley size for different designs. I produced 3 STL files for GT2 pulleys with 16, 20, and 40 teeth. For 16/20 teeth applications, consider using a flanged ball bearing on the idler end: Flanged 8mm x 12mm x 3.5mm bearings can be found at http://www.aliexpress.com/item/Flanged-8mm-x-12mm-x-3-5mm-Metal-Sealed-Deep-Groove-Ball-Bearing-10pcs/1341229739.html
