This is definitely something that can be improved. However, I mounted the couplers in a bench vice and carefully tapped the pneumatic fittings in by applying pressure while turning with a box wrench. (This is why I recommend PLA-ST or another \"tough\" filament.)\u003c\/li\u003e\n\u003cli\u003eYou may need to add a longer PTFE tube to the printer so there is enough slack to fully engage the pneumatic fitting. Use your best judgment here, just make sure the toolhead can access the entire print surface.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOpportunities for Improvement:\u003c\/strong\u003e\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eThreads for the pneumatic fittings would be nice.\u003c\/li\u003e\n\u003cli\u003eSource magnets that are less expensive than those linked in the BoM.\u003c\/li\u003e\n\u003c\/ol\u003e\u003cp\u003eDesign by banasiak on MakerWorld (license: BY-SA).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67399905575216,"sku":null,"price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_18ec4cf3-6073-418a-bbf6-d40a605a7a8a.png?v=1784916030","url":"https:\/\/mymadmanlab.com\/products\/bambu-lab-ams-magnetic-coupler","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
