DPGE: Double Planetary Gearbox Extruder (beta)

thingiverse

This is a beta version of my double extruder with planetary gear. The gear ratio is 1: 4,444. The function is uncertain when all parts are fully tested yet. However functioning prototype I made with only one level very well so this will also work flawlessly. Main block holding the motors (NEMA 17) has a fastening plate with holes 2 at 88mm distance. This then I adapted the part of sitting on top of my P3Steel frame. I have designed this for the trains to be printed separately in durable materials. Type ABS or nylon. The remaining parts do I do with a different material. For example, PLA. You have to cut the output shaft into the stepper motor a little bit of everything to suit. Remember that it takes 6st planet gears in this! The design is in the current mode NOT TESTED! Some faults can occur in both the design and text. Translated with Google Translate, some errors may occur. BOM Nuts & Bolts 8x M3x25 4x M3x20 4x M3 Nuts 6x M3x15 (actually 11) 2x M5x40 The Extruder things I used an all-metal extruder kit from AliExpress as the basis of the extruder. The parts that come from there is the bridge to lock the filament feed wheel, slave wheel tightening screw, spring, pins and the nut to sett pressure.
