Giá đỡ kệ đạn cho súng ngắn 9mm

A few months ago I found online and printed a magazine stand model that I really liked that could hold magazines upright. I recently needed to print some more but I had deleted the STL and could not find it anywhere online. Decided to recreate it in Tinkercad.  If anyone knows who the original designer or where the original STLs can be found, please let me know as I'd like to attribute this to them.

This particular model fits 9mm pistol mags. I use them on SIG, CZ, and Glock mags. If you prefer to hang magazines off of these, I have attached them using velcro to the underside of the shelves in my safe and store them that way too.
