So I made these for my "Quittin' Time Ray" figure from Diamond select. They are entirely made from styrene, model kit sprues and a straw from some WD-40. I used fastener ties for the cables. Even added a teeny-tiny, styrene smoke for Ray which is only 0.075 mm long.
Cool. Considering there's 2 recent Transformers x Ghostbusters toys released, you should see if the bots can hold them. Ectotron is obviously the cheaper of the two and would need a 5mm peg / adapter.
Damn, sometimes I forget how effective simple kitbashing can be in the age of 3d printing. These look immaculate.
