A clean weight reduction mod for the Razer Orochi v2.
Massive props to Razer for releasing such a good mouse!

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.
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.
