Demon Blood Sword - Finn's Sword

Updated: Sep 20, 2020

No need to slay the mighty demon Kee-Oth or traverse a dungeon to claim this Demon Blood Sword!

Who didn't want to wield (arguably) Finn's most iconic sword? Adventure Time is my favorite show and being able to bring this sword to life and have it mounted up on my wall brings just a little bit of the magic of the show to life.


Major Features


Each piece of the blade comes with large alignment features that works to ensure that the pieces are joined accurately and in such a way to minimize flexing on the blade. The alignment holes also feature some draft at the end to ensure that none of the blade pieces require supports.

Blade Tip Guard

This sword comes with a blade tip guard that allows you to clamp the sword together when glueing in such a way that will prevent your clamp from damaging the blade tip and ensure you are getting accurate longitudinal compression.

Cross & Cross Arms

The Cross Guard of the sword is broken up into one central "cross" and two arms. These two pieces are joined by their own set of alignment pegs. Little to no supports required depending on your printer settings. The Central Cross piece features an insertion point for the Hilt and it features the external attachment point for the blade.


The hilt features the demonic inscription from the show. It also fits neatly into the Cross Guard and the Pommel


The Pommel features the Demon Tooth and Tooth Casing as two separate pieces for easier painting. Fit with each other and the hilt very easily.

Minimalist Wall Mount

Some wall mounts were included in the model as well and were designed to accommodate small drywall screws. The mounts included were designed with the intent of mounting the sword vertically by the inside of the cross.



This is the current state of my Demon Blood Sword. The Blade Pieces are all glued together and the Cross is all glued together but I have yet to join them. As you can see the hilt and pommel are finished. On the hilt you can see the glossy red that I will be using on the rest of the sword. I have also bought some red vinyl that I will use for the hilt grip.

Here you can see the blade tip guard in action, allowing me to glue all the pieces together. I used some PVC cement in the alignment holes and Loctite super glue on the edges.

I went with supports in the grooves of the cross which may have been more trouble than it was worth (I printed it laying down). The sanding has proven really annoying in these spots which is why I took a break to complete my Finn Sword (which I really recommend checking out).


What Next?

If you are looking to create you own models like this one feel free to checkout all of my tutorials on 3D modeling and prop making techniques.

If you are looking to purchase the model so that you can print your own you can find it in the store.

Thank you for your time
