Turn your ASUS ROG Flow Z13 into a handheld gaming monster?! That’s exactly what I did.
In this video, I build a custom handheld setup using 3D printed rails and Legion Go controllers, creating what I call the “Blasphemous Beast.” This DIY mod transforms the Z13 into a portable gaming powerhouse—but it’s not without compromises.
I’ll show you:
How the 3D printed rail system works
How to connect and pair Legion Go controllers
The biggest flaws (and how Version 2 fixes them)
Real-world usability as a handheld gaming device
Charging issues and the improved passthrough solution
⚠️ This is NOT a perfect handheld—but it’s one of the most powerful DIY setups you can build right now.
💡 3D print files will be available FREE for the community!
