Hey crypto, your work always surprises me, love the helmet and the start of the plasma pistol.
and
for 1 it is only when you are making money off their property that they send their pack of IP lawyers, from their cages from where they dwell.
that's why if you build your own suit they can't touch you. their was a guy selling a casted space marine helmet that he made him self and got a very nasty shock. Also another guy who is making a full space marine costume on the RPF was selling some helmets as well and went on holiday and got back too find a cease and desist letter under his door mat, from GW's IP lawyers.
so as long as you don't sell any bits associated with GW you should be ok.
also have a look at these guys in china.
