I'm mainly doing this because I currently don't have a working printer, and quite a few of my designs (such as #Teti [gd0022]) are dual colour prints. Conveniently, I bought loads of white filament, and it would be great to just buy 3 more spools to get any specific hue I want, such as the elusive milky green (#b7c1b0).
I want to allow for feature expansion should I need it, but FDM 3D printing in general is looking like it's plateaued when I've got the #SecSavr Suspense [gd0105] to bring into reality, so I'd rather just focus on the main aim to finish what I started over 5 years ago (I bought a diamond hotend for my CR10 and never installed it).
