Hiya chooms! I was so excited to see that we finally got a proper thermal katana in the new patch, so I decided I was going to make it in real life. I 3D modelled the entire thing in Fusion 360, and it can easily be printed on a standard FDM printer. The design features a place to include a rechargeable 9v battery, allowing me to recharge my prop indefinitely, and there’s a small switch on the underside of the handle. The thermal blade part is printed in red translucent PLA, and a LED light strip runs along the inside to make it glow.
Everything was printed on my elegoo Neptune 3 Max FDM printer, however I specifically designed it to be printable on a standard Ender 3-sized printer. All the wiring is hidden via internal channels, with the end “cap” of the katana handle detaching and revealing the USB charging port on the battery.
If by any chance you’re interested in making your own, I wrote up assembly instructions and included a list of materials you need, along with the 3D files on my Kofi:

I can also help you through the process of building it if you message me on Instagram @xglorifyingx! There you can also find a ton of progress pictures/videos my own build.
Hope you like it chooms!

Wow so very cool š
Forgot to mention that the Oni mask was printed by me as well, by modifying files provided by SeanAranda : https://www.thingiverse.com/thing:4563922
I added LEDs into the lower two fangs to get them to glow.
Nice <3
U wouldnt happen to be selling them right? Like already made or whatever

Bruh, I’m spending too much time playing cyberpunk. I deadass looked at op and the first thought “I wonder what mods she is using to make her cahracter look so good.”š
Looks amazing! Just followed on Twitch as well! If you need any OBS/StreamLabs help lmk!
I saw the picture before I saw the post title – I thought this was taken on photo mode. Great job! Love the Errata, favorite weapon in the game
That’s the most tasteful and well done cosplay I’ve seen. I thought this was like fan art or something not an actual person dressed uplol
Sick!
Is it flammable?
Someone followed the crafting perk tree, huh? So incredibly cool. I mean everything, not just the awesome katana!
That was cool love the Errata and Oni mask. Using Oni Masks for my Corpo Assasin. One with all white and another one all black. In some of the pictures you look like Psychloke if she got booted to Night City.
I’ll take two.
I will gladly be your first victim.
I read the title wrong and thought you 3d printed and painted yourself, very nice work
I really thought that was in game at first haha. Looks incredible.
you look like a render from the game holy shit. Noicceeeee
I legit thought the first image was a screenshot and Iām not sure if that reflects better in the quality of the game or on your ability to mimic it so well
Daaamn that looks incredible!
holy shit do you have the STL for this? i thought this was a screenshot at first glance.
Why did I think this was a screenshot for the first like 5 photos before I read the title again
What katana?
That is bad ass. Well fucking doonnnneeeee choom
