{"product_id":"ender-3-v3-ke-fan-duct","title":"Ender 3 V3 KE Fan Duct","description":"\u003cp\u003eMy updated version of a common Ender 3 V3 KE upgrade. This modified fan duct features a lower profile design, that allows better visibility of the printhead, and easier access to the nozzle.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThis remix adds the honeycomb pattern brace to the front, as well as some extra material to the fan mounts, as they were prone to breaking before. I have had several of the original models shear along the screw holes. This updated model is still running strong for me!\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003ePlease be careful not to tighten down the fans too tightly, as you may separate the layers and weaken the fan ducts if overtightened.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eI have printed the fan duct in PETG-CF for its increased heat resistance and strength. Avoid PLA or any material with a low softening temperature. Normal PETG or any engineering filament should do the trick. Be aware that the model MAY warp\/disfigure over time do to heat exposure. I printed mine with a stronger preset with more walls, top and bottom layers, as well as 40% infill.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThis model uses all stock parts (you can add one extra screw to fix mount to extruder - not neccessary).\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eBest of luck and happy printing!\u003c\/p\u003e\u003cp\u003eDesign by moneyREID10 on MakerWorld (license: BY-SA).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67391335203120,"sku":null,"price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_be248fe8-2793-474f-b31d-5ea8b85eaab0.png?v=1784747669","url":"https:\/\/mymadmanlab.com\/products\/ender-3-v3-ke-fan-duct","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
