3D printed in PLA or PETG (depends on colour), designed to be rather thick to maximise rigidity/strength, especially due to its large size and capacity. Comes in various colours. I also do limited runs of carbon fibre PC versions for even more stiffness, but for an increased price.
New design is 5/8 mic stand thread only as that is what most people tend to buy, can be used with smaller threads with easily available adapters.
