Da fastest way to get your boyz to battle!!!
Couple of them will explode in the process, but a lound big BOOM is just a music for an ork ear.
I'm not 100% sure about the scale (maybe will need a little scale down, maybe to ~90%), but hope there will be some people to try print it and make it clear.
So anyway - print it, stick it to a boyz back - stormboyz are ready to smash and crash)))
PS For some weired reason I can not see my models in the thingieverse preview window, so sorry if they are upside down or turned under strange angle
