Some people just want bread and jam. Others want to share in the awesome power of the Chainsaw Devil Pochita to terrify their neighbors and/or win a costume contest. With some electronic components and your 3D printer (230 x 230 x 250 mm or larger), you can join me in doing so. However, sadly you cannot yet print bread and jam. Or banana bread, for that matter.

I hope this post explains my absence in the past few months. This took awhile. It goes without saying that this is my most advanced project, with far more components than any of the others thus far. The technical challenges in designing, printing, assembling, and wearing three functional chainsaws are not for the faint of heart. I can confidently say that this design is safer than it looks, as the chainsaws are plastic with blunted teeth, and all moving parts are isolated from the wearer. Once again, these chainsaws are props, but please be careful and considerate if wearing/running them.

Now, lets talk about some design features:

No glue or off-the-shelf fasteners. Everything assembles one piece at a time, like all my projects.
No supports needed when printing. Supports may help, but I managed fine without them.
Moveable jaw, with TPU flexible components
Eye holes throughout the mouth area for safety when walking/moving
222 teeth (32 in the mouth, 70 on each arm saw, and 50 on the head saw)
Potentiometer (power switch) control for all three saws on one arm, which is reachable while wearing
No coding or programmable computers involved in the electronics
Mobile power pack with belt clip, plus other accomodations for integrated electronics (see Off-The-Shelf Electronics List)
Option to print and build everything non-motorized without integrated electronics

I'm excited to share this project with y'all, and I hope a few of you are brave enough to take it on. It's a rewarding journey to put it all together, and there are many fun quirks and details within the components. However, there will be unforeseeable challenges if you take on this project. I will try to answer your questions as they arise in the FAQ section below, but I can't answer them all. This is a project for advanced or expert makers. If you haven't printed my designs before, I can't recommend starting with this one (not least because it requires five colors of PLA, one color of TPU, and likely multiple spools of certain colors).

Also, there is a minor amount of soldering involved in the electronics (six connections necessary to wire up the three DC gearmotors). I recommend learning to solder before trying it out on this project. I shouldn't have to say this to people who play with molten plastic for fun, but please be careful around high-heat devices like soldering irons. Wear eye and hand protection. "Safety first," said the man wearing the homemade chainsaws.

As with my other projects, remixing is permitted, and CC-Attribution allows this design to be reposted as long as I am credited as its designer. There is no excuse for someone passing off my work as their own.

Speaking of which, this project is deeply and respectfully inspired by the stories, art, and characters of Tatsuki Fujimoto, as well as the magnificent adaptation by the writers and artists of Studio MAPPA. Without them, I could not have brought this strange costume to life.

This one's for the devil hunters. Now go make Pochita proud.
