As a starting point for this Sourcing Guide, I based my Sourcing Guide on @shammy#6484 Sourcing Guide. I want to thank @Shammy#6484 for sharing his Sourcing_Guide with me when I needed one.
I reviewed the "generated_bom" tab, "Voron Afterburner Parts" tab, and the "Voron Optional Parts" tab in @shammy#6484's Sourcing Guide to see if any changes needed to be made. @Shammy#6484 had a tab labeled "Voron 2.4 350" where he listed his cost per part and the quanity he purchased for his Voron 2.4 300 mm³ build.
My build is 250 mm³. So the changes you will see are due to the size difference. I erased all his cost information and edited the items listed to buy. I erased all his URL links so that I could enter my URL links. Furthermore, I do not list the cost information. You can do that if you want. My Sourcing Guide is not for me to total my cost, it is basically a way to let you know where I purchased most of my parts for the Voron 2.4 build.
The QUEEN Sourcing Guide is contained in a file called "QUEEN_Sourcing_BOM.xlsx" which is inside a .zip file called "QUEEN_Sourcing_BOM.xlsx.zip". This makes it easier to download the Excel spreadsheet from GitHub since it is contained within a .zip file.
