MasterSpool Remix

All credit for the idea goes to RichRap and his MasterSpool. You can find more information at https://www.thingiverse.com/thing:2769823 and https://richrap.blogspot.com/2018/01/masterspool-proposed-standard-for-3d.html. I like the concept of saving shipping and production costs, and DasFilament is my main filament supplier. Therefore, I needed a MasterSpool 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 designed with aesthetics in mind; I wanted a design that pleased my eyes. Another goal was to save filament, so I designed the side wall thickness at 1.6 mm and aimed for overall lightness. I printed this using 160g of PETG filament (120g part 1, 40g part 2). Additionally, I experimented with modeled and printed threads for the first time; they turned out perfect for me. This design is based on RichRap's version V2, with some holes around the outer diameter and radial holes on the base cylinder to secure the filament in place. I also changed the outer diameter to 198mm to fit my printer. Since I use filament clips, the outer holes will not be used often (https://www.thingiverse.com/thing:12516). Model units are in millimeters. I hope you like my hexagonal approach. The print came out great and is definitely strong and sturdy enough. ***EDIT 2018-04-23*** I added .stp and Fusion 360 files.
