The gear ratio is 2:1 which provides a good balance between torque and speed.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThe joint part prints in place, requiring only M3 bolts to mount the NEMA 17 stepper motor. The tolerances (gaps) can be modified in the OpenSCAD file provided. If you find the joint is stuck after printing, a gentle knock with a hammer may be required to release it.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eI have since made a robotic arm based on this design too: \u003ca target=\"_blank\" href=\"https:\/\/www.thingiverse.com\/thing:4546364\" rel=\"nofollow noopener\"\u003ehttps:\/\/www.thingiverse.com\/thing:4546364\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eEnjoy :)\u003c\/p\u003e\u003cp\u003eDesign by keeeal on MakerWorld (license: BY).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67382529491248,"sku":null,"price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_3a88a7d9-fe2c-4dc8-bfba-aa334c056453.png?v=1784478648","url":"https:\/\/mymadmanlab.com\/products\/nema-17-gear-joint-print-in-place","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
