Anton Ivanov's from Zenless Zone Zero now in 3D printable form for cosplay / prop etc.!
Drill size: 96cm x 17,5cm x 18,6cm
For the support: 12⌀mm wide and 55cm long dowel/pipe and 3 x 8⌀mm wide 40cm long dowel/pipe.
Everything comes ready to print in 9 STL parts + clip for the dangling wiring. It is not printable option at the moment, but if you rather prefer it I can provide it as it is modelled for the looks, though I don't recommend it and instead recommend to use material like thick rubber-like band (1,2cm wide and 0,5cm thick) for realistic look.
Not for resale!
