Light-UP K-Pop:Demon hunter sword coming soon !!!

As you might have guessed, I’m working on Rumi’s sword from K-Pop: Demon Hunter!

But I couldn’t just make regular 3D models and leave you to figure it all out — so I went a bit overboard and decided to solve all the requests you guys had in the FB group.

The main requirements/challenges were:

  1. It has to be easy to print

  2. It has to be collapsible, so it’s easy to transport

  3. It needs a non-expensive, simple light-up system

  4. It should have solid strength and durability

I think I’ve managed to solve all of that. Big shoutout to Anthony Townsend for the blade suggestion idea — it really helped tie the whole design together.

I’m test-printing everything now, and if all goes well, it should be ready for you guys very soon! :)

Can anyone share best way to blend the blade lines (putty, paint, etc) this lighting up, would think the lines might be painfully visible - open to suggestions

I waited for this because I knew you would do it the Marko way which is always the best, this will be a Christmas present for my daughter.

Is there anyway you can give us alternatives to Ali express? I live in the US and Amazon seems to be the way to go here. If you can help that would be great.

I knew it was coming but I couldn’t wait to see if it was going to be before Halloween. I’ve made both Mira and Rumi’s weapons for my daughter :) I’ll have to print this one for me though.

if you can give us a hint as to what is needed for lighting so we can pre-order stuff, that would be amazing. :D
