made a complete redesign with this Remix. Goal was to excange the printed and fast breaking clips with a (metric) Screw to fix the wheels to the base. You Need one M3x8mm Screw for every gear.gear design is "very close" to metric gears with modul 1. i´ve printed the first ones with 0.5mm nozzle, should better be done with a 0.25mm nozzle... will upload a few more bases soon... :) Thanks to Umake for the Inspiration! UPDATE ======= added a upside-down Version of the gears to get the glossy side up when printing abs directly on glass. this ones have the hole closed with a 0.5mm thin wall to make em printable without support. the wall needs to get drilled after printing... added: base for Z20-Z40 two Z40 gears with one or two grooves Z20, Z30 and Z40 gears with a knob (thanks to Bobovich) ‘halter_five_4xZ14_1xZ20.stl’ added: triple_opend_Z20-30-40_complete duo_opend_Z20-40_complete.stl duo_opend_Z14-20_complete.stl five_opend_4xZ14_1xZ20.stlPLZ add pics if you made one. :)
