this is what i'm thinking for the painted/modded nerf blaster, but i'm having issues w/ my 3d printer (aka it was delivered monday and i haven't had time to calibrate it yet) & the blasters are being painted, so don't want to use my calipers on them right now, so can't get exact measurements & adjustments done

this would be the right side clip, with the parallel clips grabbing the guard between the triggers, and the perpendicular shelf supports the weight of the blaster to keep the other clips from sliding up & hitting the triggers.
sketchup file's been shared here if someone else wants to grab it & tweak it for everyone to use.

I'm surprised you're going with a vertical clip for the bottom trigger guard. My Nerf blaster doesn't have much space between the trigger and forward trigger guard to fit a clip. Originally I was thinking of making a horizontal clip for the forward trigger guard in front of the bottom trigger button. Plenty of space there! Post pictures when you complete yours. I'd like to see how they turn out
