I always somehow peak at the end and really do not enjoy the new season MMR cut. But ending at exactly 600 matches is pretty neat! Who says tarantula is trash unit???

[Completed] 26cm Custom Mech - 3D Printed, Airbrushed, and Weathered with hidden Arduino Lighting

Hey everyone! I spent the last two months building this 26cm Arclight mech from game called Mechabellum. Since no commercial kit exists, I printed the parts in resin, but that was just the very beginning of the modeling process.

The build involved heavy sanding, gap filling, and assembly. I airbrushed the base coats and spent hours hand-painting the weathering, chipping, and panel lines to give it a heavy, battle-worn look.

I also scratch-built a custom Arduino circuit hidden entirely inside the base. I routed the wiring on resin legs up to the main gun to create a programmed, pulsing plasma effect, rather than just a static LED.

Here is a short video showing the finished model and the lighting effects: https://youtu.be/j-kDCAcnu0o

Would love to hear your thoughts on the weathering job or how you guys manage wiring in custom builds!

My first major mixed-media build: 26cm Resin Mech + FDM Base with embedded Arduino lighting (80+ hours of work)

Hey makers!

I spent the last two months (easily 50-80 hours of work) putting together my very first complex physical model. It’s a level 1 Guilded Arclight from the game Mechabellum, standing at 26cm tall. It was one hell of a journey, but I’m incredibly proud of how it turned out.

The Build Details:

  • The Mech (Resin): The entire body was printed in resin to capture all the sharp mechanical details and panel lines.
  • The Base (FDM): I used an FDM printer for the stand to give it structural strength and to create a hollow chamber.
  • Post-Processing: Lots of sanding, assembling, airbrushing, and hand-painting the weathering/guilded details.

The Electronics: I didn't want it to be just a static piece, so I embedded a custom Arduino circuit inside the FDM base, running wires through the resin legs. The main gun features a glowing reactor effect with 4 switchable modes:

  1. Basic attack interval (0.9sec pulse)
  2. Charged shot interval (1.2sec pulse with a heavy wind-up)
  3. Slow ambient pulsing (idle mode)
  4. Gun malfunction

Since this was my first time tackling a project of this scale (especially the coding and electronics), I heavily relied on an AI assistant to guide me through the circuit diagrams and code logic. I pasted our conversation into a doc afterwards, and it was over 320 pages long!

I made Arclight IRL (26cm physical hand-painted model with light effects)

StillI love playing Mechabellum, so I thought it would be a cool idea to make a physical model of level 1 guilded Arclight! (26cm hight size). It is mostly a resin 3d print with FMD stand with built in eletronics for main gun light effects and blue ambient lighting - airbrushed and handpainted, with electronics inside the stand.

I spent last two months to gradually make this, it was a journey!

The gun has 4 basic modes you can switch:

  1. start up effect and basic arclight shooting with 0,9sec interval
  2. different start-up effect with charge shot 1,2sec attack interval
  3. slow gun ambient pulsating
  4. gun malfunction

This is my first model, so huge shout out to AI that helped a TON in making this.
I pasted our conversation to doc to see how long it is and it has 320 pages of text.
I estimate like 50-80 hours of work in total, maybe more....

Hope you like it!

I used Arduino for the main gun of a cool mech from a video game I like

I 3D printed this mech and wanted to give it a realistic, pulsing reactor core and blue atmospheric ambient light. I managed to hide the entire circuit inside the base.

The Hardware:

  • Arduino (brain)
  • Li-Po battery + TP4056 (USB-C charging) + Step-up converter
  • WAGO connectors (absolute lifesavers for tight spaces!)
  • 1 main Amber LED (reactor) + Blue LEDs (underglow)

The Code: A simple sine-wave fade looked too artificial. I let AI to code a custom non-linear pulse (see my sketch in the first comment pic) with a sharp ramp-up and an organic fade-out to make it look like unstable plasma.

In total is has 4 stages - main shooting, teched shooting with different startup, atmospheric pulsing and gun malfunction...

This is my very first electronics project – let me know what you think!

I made an Arclight - battle mech from my favorite video game

I love playing the game Mechabellum, so I thought it would be cool to make a physical model out of it (26cm hight size). It is mostly a resin 3d print with FMD stand with built in eletronics for main gun light effects and blue ambient lighting - airbrushed and handpainted.

This is my first model, so huge shout out to AI that helped a TON in making this.
I pasted our conversation to doc to see how long it is and it has 320 pages of text :D

Hope you like it!
