This is the reason I built my RapMan :DI've made a shell to go around a (heavily modified) Nerf Stampede to make it look like a 40k Bolter.It's still fully functional, shoots darts and takes standard Nerf magazines (one day I'll do the Bolter magazine too)Unfortunately it'll always be more a decorative piece, mostly due to it weighing 4kgs, making far too heavy to lug around all day during wars or HvZ :PNot quite sure what's going on in the preview images for the .STL's, They printed out ok after a bit of rotating in Axon(Obligatory Note: I don't own Nerf, or anything relating to GamesWorkshop/Warhammer, etc, I'm just a big fan of both)The Stampede had to be minimised to make it fit, as shown in the picture comparing the lengthsFor interest it's also running an aftermarket 9kg spring, and 2 banks (in parallel) of 4x Trustfire Lithium batteries for ~16v
