This is the A\/B motor pulley on a Voron 2.4, Trident and Monolith, and on most other CoreXY printers with 5 mm motor shafts.\u003c\/p\u003e\n\u003cp\u003eRunice is the pulley brand Ducklabs Motion ships with their Gates belts, and the reason I picked it over the generic ones: the teeth are machined cleanly and the bore is actually 5.0 mm, so the pulley sits straight on the shaft instead of wobbling. Pair it with a Gates belt and the drive side of your gantry is sorted.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTeeth: 20, 2GT (2 mm pitch)\u003c\/li\u003e\n\u003cli\u003eBore: 5 mm, 2 grub screws\u003c\/li\u003e\n\u003cli\u003eBelt width: 9 or 10 mm\u003c\/li\u003e\n\u003cli\u003eMaterial: aluminium\u003c\/li\u003e\n\u003cli\u003ePrice is per pulley\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Runice","offers":[{"title":"Default Title","offer_id":55537637458247,"sku":"RUNICE-20T-2GT-5-PULLEY","price":5.45,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0878\/0575\/5719\/files\/PXL_20260422_211645312.jpg?v=1792762122","url":"https:\/\/pjotr3dshop.com\/de\/products\/runice-20t-2gt-pulley-5-mm-bore-for-9-10-mm-belts","provider":"Pjotr3DShop","version":"1.0","type":"link"}
