This model does not have moving parts nor can it be modified to be functional. This is a solid, static prop.
This model is my take on the Bolter from Warhammer Darktide and features two different scales, human sized (75% scale) and Space Marine sized (100%).
This is a very hefty model, taking up nearly 2 kgs of material at full scale.
It is split into 12 pieces for easy printing on a Bambu sized printer.
