This is \u003cstrong\u003e1.75 meters of 2GT (GT2) timing belt at 3mm\n  width\u003c\/strong\u003e — the correct profile and width for the Positron V3.2's XY and Z belt-driven\n  motion system. If you're building a Positron from scratch, maintaining an existing machine,\n  or replacing a belt after a crash or excessive wear, this is the correct spec to order.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  ⚠️ \u003cstrong\u003ePositron V3.2 specific.\u003c\/strong\u003e This belt is not compatible with the original\n  Positron V3.0, which used synchromesh wire instead of GT2 belts. The switch to 3mm 2GT\n  belts was introduced in V3.2 specifically for easier maintenance and sourcing.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003eDo not cut your belts until final assembly is confirmed.\u003c\/strong\u003e Route and\n  tension both axes fully before trimming any excess length.\n\u003c\/p\u003e\n\n\u003ch3\u003e3mm Width — Why the Positron Uses a Non-Standard Belt Size\u003c\/h3\u003e\n\u003cp\u003e\n  Most desktop 3D printers use \u003cstrong\u003e6mm wide 2GT belt\u003c\/strong\u003e. The Positron V3.2 uses\n  \u003cstrong\u003e3mm wide 2GT belt\u003c\/strong\u003e — half the width — as a deliberate design decision\n  driven by the printer's extreme compactness and lightweight toolhead requirements. Narrower\n  belt reduces mass on the motion system and fits within the tight geometry of the Positron's\n  folding CoreXY architecture without compromising the 2GT tooth profile, which remains\n  identical to standard GT2. This means the belt engages correctly with standard 2GT pulleys\n  and idlers — just at 3mm width rather than 6mm. Sourcing the wrong width (6mm) is the most\n  common belt replacement mistake on the Positron — this kit has the correct 3mm spec.\n\u003c\/p\u003e\n\n\u003ch3\u003eFull Replacement Length for XY and Z Axes\u003c\/h3\u003e\n\u003cp\u003e\n  The Positron V3.2's motion system is fully belt-driven across all axes: a single continuous\n  belt handles both X and Y movement, and a separate belt drives the Z column — all running\n  on 3mm 2GT profile with LDO linear rails and 20-tooth pulleys. The \u003cstrong\u003e1.75-meter\n  length\u003c\/strong\u003e of this kit covers the full belt requirement for a complete replacement of\n  the Positron V3.2 motion system. Some excess length is expected after routing and tensioning\n  — do not pre-cut before verifying final routing.\n\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLDO Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBelt profile\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2GT (GT2)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBelt width\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTotal length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.75 meters (1750mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible printer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePositron V3.2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNOT compatible with\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePositron V3.0 (uses synchromesh wire)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePulley compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2GT 20-tooth, 5mm bore, 3mm belt (LDO Positron spec)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAxes covered\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eXY motion belt + Z axis belt\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e✅\u003c\/td\u003e\n\u003ctd\u003e1.75 meters of 2GT 3mm timing belt\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's NOT Included\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003e2GT idlers — sold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003e2GT pulleys (20T, 5mm bore) — sold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003ePositron V3.2 full kit — sold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhen Do You Need This?\u003c\/h3\u003e\n\u003cp\u003e\n  Order this if you're: building a Positron V3.2 from BOM and need to source belts independently,\n  replacing a worn or snapped belt after extended use, or stocking a spare for a printer you\n  travel with regularly. Because the Positron is a portable printer that gets folded and\n  deployed repeatedly, its motion components — especially belts — see more mechanical stress\n  than a stationary machine. Having a replacement belt on hand costs less than a delayed build\n  or a grounded printer on the road.\n\u003c\/p\u003e\n\n\u003ch3\u003eResources\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n    \u003ca href=\"https:\/\/wiki.positron3d.com\" target=\"_blank\" rel=\"noopener\"\u003e\n      Positron Wiki — official build documentation and BOM\n    \u003c\/a\u003e\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003ca href=\"https:\/\/ldomotion.com\/p\/assembly\/Positron-V32\" target=\"_blank\" rel=\"noopener\"\u003e\n      LDO Positron V3.2 Assembly Guide — belt routing and tensioning instructions\n    \u003c\/a\u003e\n  \u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Browse the full selection of Positron-compatible motion components at\n  \u003ca href=\"\/collections\/3d-printer-belts-pulleys\"\u003e3D Printer Belts \u0026amp; Pulleys\u003c\/a\u003e, or\n  explore all motion system parts 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":"Default Title","offer_id":52735673205030,"sku":"LDO2442","price":3.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/1986\/2822\/files\/positron-3mm-belt-kit-2gt-175-meters-west3d-3d-printing-supplies-ldo-systems-434717.jpg?v=1773259451","url":"https:\/\/supplies3d.shop\/products\/positron-3mm-belt-kit-2gt-1-75-meters","provider":"SUPPLIES3D","version":"1.0","type":"link"}
