Summary That nice-printin' bacteriophage now with a hollow space in the icosahedron for storing a single pill and a hole at the injection point for adding a 6 mm x 8 mm cylindrical magnet! Update: tweaked the model and printed the thing up... Not enough cooling on the underside of the head, so it got a little gooey, and I the cap was printed normally oriented with supports for the little overhanging edges, so the cap doesn't match up really nice with the bottom. The fit is just about right, though. Maybe it needs a little catch or thread? Print Settings Printer Brand: Printrbot Printer: Simple Black Rafts: No Supports: Yes Resolution: 0.2 mm Infill: 20%
