I have spoken with a bunch of people at those events who say they make their armour pieces, and even helmets with them.

I really want to buy a 3D printer, I design stuff on Blender so would love to get into printing. Especially when it comes to making models/ dioramas.

What one do you have? I was looking at a Bambu Lab one, it is enclosed. Costs about 650/ 700 with the four filament holder on top
