Hello
This is a mixture of speed strip and speedloader.
3D prints in one part.
No moving parts, only bending parts.
Youtube demo:
KULLI™ - a K-frame S&W revolver loading aid by h0rstik4inen - Thingiverse
Tested on the range. I built 13 loaders, loaded them full, went to range, used them. One cracked a part when printed from hard PLA plastic. Cost per unit : 15c so I just ditched it.
No preview photos, I switched from Mac to Windows10 and ... everything is now painful to do. Like copying a couple of photos to imgur.
You load 3 rounds twice.
PROs:
No need for a speed loader cut in the grip.
No need for a clip cut in the cylinder.
Cheap.
Simple.
Faster than speedstrips where you load 2 rounds 3 times.
CONs: slower than moonclips or speedloaders.
I haven't seen a thing just like these before so, have fun. It seems to be an original idea.
