However, due to variations in dimensional accuracy from printer to printer, you may find the filament does not fit snuggly into the groove. In such cases, apply a small amount of glue along the groove before pressing the filament into place, and allow the glue to fully set before using.\u003c\/li\u003e\n\u003c\/ol\u003e\u003cfigure class=\"media\"\u003e\u003coembed url=\"https:\/\/youtu.be\/HEJGvU5l2t0?si=fW9fqMHewVJJlHsV\"\u003e\u003c\/oembed\u003e\u003c\/figure\u003e\u003ch2\u003eExtraction Tools\u003c\/h2\u003e\u003cp\u003eThe adapters can be a very tight fit on the spool spindles, and difficult to take off once on.

Of the four I have to test with, no two are alike and require different amounts of pressure to press on\/off the adapters. Likewise, one of the spool spindles is a full three millimeters longer than the others for some reason. For cases where the spool adapter is too short, it will leave a slight gap between the spool and adapter where the adapter can't seat itself fully against the spool. I don't anticipate this will cause any issues, but if you use the adapter and have a gap, and it does cause issues for you, please reach out.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ch2\u003eAcknowledgements\u003c\/h2\u003e\u003cp\u003eThe following people and makes have contributed ideas to this model:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003ca target=\"_blank\" rel=\"noopener noreferrer ugc\" href=\"https:\/\/makerworld.com\/en\/models\/752155#profileId-686016\"\u003eFunctional Print Friday - Spool Buddy\u003c\/a\u003e - Sight line, visibility dot, tapered end \u003c\/li\u003e\n\u003cli\u003e\n\u003ca target=\"_blank\" rel=\"noopener noreferrer ugc\" href=\"https:\/\/makerworld.com\/en\/models\/698372#profileId-820919\"\u003eOne Maker Show - “Sunbu” Spool Adapater\u003c\/a\u003e - Original concept\u003c\/li\u003e\n\u003cli\u003e\n\u003ca target=\"_blank\" rel=\"noopener noreferrer ugc\" href=\"https:\/\/makerworld.com\/en\/models\/823944?from=search#profileId-767379\"\u003eYesiotr - Sunlu→Bambu Refill Adapter\u003c\/a\u003e - Integrated AMS Lite adapter\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eDesign by Levi on MakerWorld (license: CC0).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67439363227952,"sku":null,"price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_7da41f58-e832-442d-8f05-3e06bc9d156e.png?v=1785755956","url":"https:\/\/mymadmanlab.com\/products\/the-ultimate-sunlu-to-bambu-spool-adapter","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
