Rotofury Shotgun Cylinder

thingiverse

I had seen this mod before and the files eluded me, so here is a new shotgun cylinder for the Nerf Mega Rotofury. It is a 10 shot, 3 dart shotgun adaption for the rotofury. for how it works, look up nearlynewmodels video on youtube for the old cylinder assembly. This is what I based it from. A difference between their model and mine is that I split the priming rod at the union of the two halves, rather than cut it elsewhere. The two halves are joined with a plastic sleeve and glue, and will need to be removed in any way necessary, without damaging the rod too much. For print orientation, print the cap with the tapered end (tip) facing down, the cylinder with the base down (bottom of cylinder) and the connector up on end (vertically). Print with at least 1.2 mm walls, and 20-22% infill. .15 for the layer height works well. You will need to shave a little bit off of the locking tabs on the cap, and this is intentional so you can get a perfect fit (friction fit). You may want to reem out the holes at the bottoms of the dart tubes so the foam seal on the plunger tube doesn't tear. The cylinder is a bit tight inside the shell, so sanding the edge of the shell or adding some lube to the ends and the end of the cap would be beneficial. For anyone wondering why there are no tighter rings at the bottom of the dart tubes, the cylinder likes half length darts more, and fire 6 very well. Also I tried to get the fit to that of 17/32 brass so it is a pretty good fit.
