Summary These three parts link together to make an old style 3.5 inch disk box. I basically designed it as my other hobby is origami and boxes like this are great for carrying around standard 7.5 cm / 3 inch square origami paper, but of course they are getting harder and harder to fine as no one uses them any more. So I built this one in Autodesk Fusion 360, its a little bit of a work in progress as I think some of the connections could link together better, but the one I knocked up seems to work well for my Origami paper. Print Settings Printer: Eaglemoss Vector3 Rafts: Yes Supports: No Resolution: .2 mm Infill: 20% Notes: Whilst I think you could get away without the raft, if your heated bed works well. The one on my printer can be a bit flaky and can lead to warping with something with such big flats areas on the bed without putting it on a raft or with a brim.
