HUMBLE comes with a 2 millimetre thick Stainless Steel base and backplate which gives the case extreme rigidity even without the side panels on.
The regular side panels are also 2 millimetre thick, the material is standard, powder coated AlMg3 aluminium.
The solid brass cube joints that hold the case together give a rigid and durable connection.
With the metric M3 threads the user can change or replace side panels with ease!
