Use that number on a custom filament profile.  I would run the test for any filament you want to print at .2 because color additives can affect flow rates.  Black and white filaments can have different characteristics.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eTotal time for all 9 objects on a a1 is 2 ¼ hours and uses less than 8 grams of filament.\u003c\/p\u003e\u003cboostme\u003e\u003cboosttitle\u003eBoost Me\u003c\/boosttitle\u003e\u003cboostcontent\u003eIf this test works for you, please consider a boost.\u003c\/boostcontent\u003e\u003c\/boostme\u003e\u003cp\u003eDesign by NerdForge go on MakerWorld (license: BY).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67369413640496,"sku":null,"price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_b83e4ead-a782-410b-8bc9-71715b29f227.png?v=1784064050","url":"https:\/\/mymadmanlab.com\/products\/2-nozzle-filament-flow-test","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
