Description

Thanks for checking out my Ntron Type 2 build!

This one is something special — the darker, weirder, lilac-toned sibling to the original Ntron. Think of it as the Majora’s Mask of the series: a retro-vintage all-in-one system that blends 8-bit gaming with a fully integrated chiptune synth setup, powered by the PO-20 Arcade and the Korg Monotron Delay.

Two modes — Game Mode and Synth Mode — let you switch effortlessly between pixel nostalgia and raw 8-bit sound design.

The Type 2 is packed with thoughtful details and plenty of room for personal customization. You can keep the build simple and get it running fast, or go all-in with sanding, painting, decals and custom LED matrix messages to give it its own personality.

Downloads & Files

I recommend downloading the Ntron_Type2_All ZIP, which includes everything in one place:

3mf File
STL Files
Documentation
Decal Sheet
Pictures

You’ll find it under “Download STL”, and the documentation is also available further down this page. The 3MF file is fully prepped for the X1C and P1S, with each print plate using optimized materials, supports, brims, and orientations. Some parts include multiple design versions — be sure to read the Design Choices section in the documentation to pick the one that fits your build. The print beds are clearly named for easy reference, and the alternate part versions are placed off to the right if you want to drag them into the plate.

Filament

For this project I used matte PLA, but most materials should work just fine.
Before starting your build, please read through the entire documentation to understand the flow and options.

Software & Firmware

The image file containing Retropie, the Audio Visualizer, and all required scripts for the buttons and NES ports is available for download HERE. The INO file for the ESP32 board and LED Matrix is downloadable HERE.
It’s truly Plug ’n Play — flash it, boot it, and you’re ready.

Support & Extras

I’m committed to keeping my projects alive and improving them over time.

Thanks for checking out the Ntron Type 2 project! If you have any questions during your build — wiring, printing, assembly, software, or mods — feel free to drop a comment here and I’ll do my best to help. I’ll keep updating the documentation and print files as needed, so if you notice anything unclear or find something that can be improved, let me know! Happy building — can’t wait to see your versions of the Ntron Type 2. 💜

This is so cool! I have a couple questions/thoughts: 1. The body sections both give the following error when slicing: "G-code path goes beyond plate boundaries" and are unable to print. Even when re-orienting them they seem to be too large (P2S build plate). - switching to tree supports seems to fix this issue and cut down on a lot of filament, without adding too much time. 2. In the parts list: do I need the LED matrix driver if i'm using the LED Matrix Bonnet version? Does that not already have the driver built in? 3. It would be awesome to get the front plate in a couple of other variations. One with USB ports on the front instead of NES ports so I can use a wider variety of controllers (additional wiring diagrams for this would be great). And maybe a second with no ports, so that people can just use bluetooth/wireless controllers and skip some steps. 4. Would this run on older/other versions of the Pi? I have the original Pi 3 model B for example. Thanks so much!

Replying to @JimDynasty :

Hey! Thanks for your feedback! :) 1. Ah okey, yea it was really tight, if I nudged the body parts just a little I got it to fit. It´s the support which goes outside the build plate a little. I will update the 3mf file. 2. It should work space wise and everything, maybe some slight code adjustments needs to be done, I am not 100% sure about it though. I´ve never worked with the bonnet version myself. 3. Good Idea, I will look in to this and add some panels within a few days. 4. In this build I use a pi 3b+, with a 32gb sd card. Let me know if you have any more question :)

@JimDynasty

Thanks for the speedy reply! Looking forward to those updates. Worth noting that the version of the matrix in your list of parts is the bonnet version, which is why I was confused!

@Artifextron

Added a Front Panel to use if you want to skip the NES ports, and have two usb ports instead. The type of USB panel mount is the same as on the back, so Instead of sourcing 1 you will need 3 with this front panel.

@linkreincarnate

I see a line out and a headphone jack but does it have a line in as well? Great work btw Just got my PO arcade and waiting on my monotron,,,
