Multi-Caliber Powder Funnel with caliber inserts

My .223 brass finally popped through the mouth of the green plastic funnel I've been using for years. I was looking for an appropriate replacement for it in the form of an .stl file, but could not find one I liked. So I designed my own, and here it is. It's slightly larger than the old one, as you'll see in the comparison photo, but I'm ok with that as my fingers have gotten fatter in my old age. The loop handle is large, and ambidextrous, obviously. The hole in the center is 5mm to fast drop even large extruded powders like Varget. Wipe the whole thing down with a dryer sheet to prevent problems caused by static electricity. The bottom of the funnel is a concave cone so the mouth of your brass will touch it no matter what angle you insert the brass into, but if you prefer a tighter fit for a specific caliber, I've created 3 inserts that pressure fit into the bottom of the funnel for .45, .357, and .223. You may need to tweek the size of the insert in bambu studios
