The\n  9:1 ratio delivers higher torque multiplication and improved Z resolution, but it also\n  means the planet gears and sun gear are under real mechanical load during every extrusion\n  move. The \u003cstrong\u003e9-tooth sun gear design\u003c\/strong\u003e (divisible by 3 planets) ensures even\n  load distribution across all three planetary gears simultaneously — a deliberate engineering\n  decision that significantly reduces wear versus 10T designs where loading is uneven.\n  Even so, in high-cycle print farms, abrasive filament environments, or after a jam that\n  locked the drive mid-print, these are the components that absorb the damage. Having\n  spares on hand means a rebuild takes minutes, not a week waiting for a new kit.\n\u003c\/p\u003e\n\n\u003ch3\u003eCompatible With\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eG2E\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGalileo 2 Extruder — Voron Stealthburner drop-in replacement for Clockwork 2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eG2Z\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGalileo 2 Z-Drive — compact Z drive for Voron V2.4, Micron 120\/180\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eG2ZXL\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGalileo 2 Z XL — larger Z-drive variant using NEMA 17 motor\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eG2SA\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGalileo 2 Standalone — Orbiter 2.0 \/ Sherpa Mini drop-in (uses G2E parts)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNOT compatible\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGalileo 1 — no parts are shared between G1 and G2\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eResources\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n    \u003ca href=\"https:\/\/github.com\/JaredC01\/Galileo2\" target=\"_blank\" rel=\"noopener\"\u003e\n      JaredC01 Galileo 2 GitHub — assembly manuals, BOM, printed parts files\n    \u003c\/a\u003e\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003ca href=\"https:\/\/west3d.com\/products\/galileo-2-kit-by-jaredc01-ldo-motors-g2e-and-g2z-extruder-and-z-drive-kits\"\u003e\n      Full Galileo 2 Kit (G2E, G2Z, G2ZXL) — if you need a complete new kit\n    \u003c\/a\u003e\n  \u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Browse our full extruder selection at\n  \u003ca href=\"\/collections\/3d-printer-extruders\"\u003e3D Printer Extruders\u003c\/a\u003e, or explore all\n  drivetrain upgrades at\n  \u003ca href=\"\/collections\/3d-printer-upgrades\"\u003e3D Printer Upgrades\u003c\/a\u003e.\n\u003c\/p\u003e","brand":"West3D 3D Printing Supplies","offers":[{"title":"POM Injected Planetary Gears","offer_id":52735671959846,"sku":"LDO2090POM","price":3.99,"currency_code":"USD","in_stock":false},{"title":"Extruder Gear","offer_id":52735671992614,"sku":"LDO2091EXT","price":6.99,"currency_code":"USD","in_stock":true},{"title":"Carrier Shaft","offer_id":52735672025382,"sku":"LDO2092CAR","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/1986\/2822\/files\/galileo-2-spare-parts-planetary-gears-carrier-shaft-extruder-gear-etc-west3d-3d-printing-supplies-ldo-motors-112919.jpg?v=1773259450","url":"https:\/\/supplies3d.shop\/products\/galileo-2-spare-parts-planetary-gears-carrier-shaft-extruder-gear-etc","provider":"SUPPLIES3D","version":"1.0","type":"link"}
