Also how durable is it?
Very durable-- its fibreglass.
Interior aprox: 61x15cm | Exterior aprox: 66x20cm.
Its decently long, so you can comfortably fit a 12s4p, full size bms, and your focboxes.
Not sure if it’s worth it to just make a kydex enclsure instead, the only cons of just using eboosted’s would be fitting and customizeablity
