I spent 2 evenings modeling the Titanfall 2 Pulse Blade based on some concept graphics of our favorite throwable. More render images are available here: https://imgur.com/gallery/iJIcR0B

Designing done in Fusion 360 with 3D printing in mind. The whole thing should easily and nicely print on any FDM and resin printer. 4 Parts total, I've designed both a basic version and electronics version which fits an LED at the back of the blade, switch to arm/disarm it and a small battery to power it. This is the basic version which does not feature any spacing for electronics. It's a little bit easier to print as it has no overhangs at all. Print each of two files two times, and epoxy everything together.
