I'm a Percy Jackson fan so all Greek and Roman swords fascinate me so seeing that there was no kopis on Printables or Thingiverse was quite sad. So I made one myself (I made it printable at least).
The blades for these swords historically is typically 65 cm (25.6in) and with the handle, the whole sword ends up being roughly 83.8 cm (33in) at 100% scale. The swords were one-handed swords, hence the smaller length on this sword being closer to my khopesh model than my ikakalaka.
All of the pieces should fit onto a Prusa Mini/ Ender 2 because the largest parts are 160mm from end to end. I decided to try something new that hopefully works a lot better than my "eyeball it" method that I've been using for cutting up models. All of the dovetails have a groove depth, width, flap angle, and tolerance of 10.0mm, 12.0mm, 70°, and 0.20mm, respectively. I want the tolerance to be slightly larger than default just so it's not such a tight fit on printers that aren't as dialed in as others *cough my own cough*. In my mind it's also a funny visual to see part one connected to part five (the tip) but maybe I'm alone on that. I also put more of a traditional rectangular tang on this one rather than a circular one and having to inset the blade into the handle, so this tang should be a lot cleaner and easy to put together. Should.
As is tradition with my models, these haven't been printed yet, but they did slice correctly in both Cura and PrusaSlicer so they shouldn't give you any issues. The spine on this sword is wavy so the best way to print these will probably be vertically, and the handle is pretty flat on one side so printing that face-down will probably be easiest.
I'm not gonna lie, the render still isn't exactly pretty, but I did make it myself so maybe that cancels it out. I also added the render from the Sketchfab model because it looks great.
The author remixed this model.
I remade all of the faces of the sword blade, slimmed and moved the base of the blade, added a little tang to slot into the handle, smoothed out and slimmed down the handle, used the tang to cut a hole in the handle for it to slot into, scaled all parts to be accurate-to-life, and cut them up to fit on a Prusa Mini.
