MasterSpool Remix

All credit for the idea goes to RichRap and his MasterSpool: https://richrap.blogspot.com/2018/01/masterspool-proposed-standard-for-3d.html. I really like the concept of saving shipping and production costs, and DasFilament is my go-to filament supplier. Therefore, I needed a master spool to test the refills on my next filament order. Based on RichRap's MasterSpool dimensions, I modeled my version from scratch in Fusion 360. This remix was aimed at creating a design that pleases my eyes and saves some filament - I designed the side wall thickness to 1.6 mm and tried to make it as light as possible overall. Printed with 160g of PETG filament (120g part 1, 40g part 2). Additionally, I wanted to try using modeled and printed threads for the first time; they came out perfectly for me. I based this on RichRap's version V2, added some holes around the outer diameter, and some radial holes on the base cylinder to get the filament hooked in. Also changed the outer diameter to 198mm to fit my printer. Model units are in millimeters. I hope you like my hexagonal approach - the print came out great and is definitely strong and sturdy enough.
