orochi-superlite

A clean weight reduction mod for the Razer Orochi v2.

Massive props to Razer for releasing such a good mouse!

Background

The goal of this mod was to nondestructively reduce the weight of the mouse while maintaining functionality and structural integrity.

The stock mouse is made of 3 main parts: Lower Shell, Upper Shell, and Inner Skeleton.

I removed the Inner Skeleton of the mouse and replaced all its functions with various 3D printed parts.

The final weight of the mouse fully assembled is ~56 grams.

This image shows the correct orientation for printing each part. Add supports as you see fit.

Pros:

  • Significant weight reduction through the removal of a 14g inner hull.
  • 150mah Lipo Power System, significantly lighter than an AA battery.
  • USB-C rechargable, charges in ~40 min, lasts 50 hrs.
  • Still structurally integral
  • Uses original outer shells, so it looks stock and feels nice
  • Charging port integrates nondestrucively with the rest of the mouse
  • DPI button is moved to a nicer place, can be rebound to an in game function

Cons:

  • Still can't use the mouse while charging. The charging circuit only allows usage OR charging, one at a time.
  • Depending on what material you print with, the magnet holder might become looser over time (material creep). If the magnet pops out, it can be glued back in.
  • It's still an Orochi v2, so the shape is not for everyone.

Suggested Usage

I don't really recommend going for the Lipo variant unless you really know what you are doing. I had to crack a Lipo AA battery apart to harvest its charging circuit, which should be done with extreme caution. I also directly soldered Lipo connections to the charging circuit, but you could also just source and solder a battery connection to the circuit.

LR44 or 675 Button cells are much safer to work with. Get or print a button cell holder, and desolder the battery cable from the Inner Skeleton part of the stock Orochi, and you're in business.
