The file 'British Royal Space Guard + Banner 3D Printer Model' is (stl) file type, size is 75.6MB.
Took the free design from:
https://cults3d.com/en/3d-model/game/the-sergeant-bearskin-variant
https://cults3d.com/en/3d-model/game/imperial-guard-standard-bearer
The only difference I made was scaled it down to 28mm-29mm and support it
