The Infinity Blade

thingiverse

I designed this model from reference images of the sword from the game, aiming to create a 3D model that's proportionally accurate and true to the blade from the game. This thing is still a work in progress, but eventually I'll have STLs up for a sectioned version of this model. In case it matters to you: The blade bevel is at 45 degrees, which should provide the proper angle for a one-handed sword. The STL is scaled to 41 inches long, and is based on human hand size for the grip. I'll post updates as needed. Update: 9/15/16 I sliced the blade into 5-inch sections, with all but one of the six pieces being exactly five inches each. The holes are scaled to accommodate 3mm filament attachment pieces. I intend to print mine from ABS since acetone welds tend to be decently strong. There will be nine pieces in total, including the center ring and pommel. The center ring might be tricky to print due to its shape, but printing with support should fix this issue. If it becomes a big enough problem, I'll post a new part without the lip on either side. Print Settings Printer Brand: LulzBot Printer: Mini Rafts: No Supports: Yes Resolution: 0.2 Infill: 10% Notes: My recommendations for printing the blade pieces are shown above. Higher infills will increase weight and put stress on the center ring. Aside from that, I'll be printing three shell layers at a nozzle width of 0.5 each. As far as the center ring goes, it may be the weakest part of the prop, so I'll likely print it at 25-40% infill. The handle will also get higher infill. The Center ring was printed at 40% infill along with the handle, and even in an enclosure, the prints warped a little. I recommend large brims on all pieces to produce the best results with ABS. Four of the blade parts were printed on a raft, which was a mistake.
