Summary

Just getting into reloading! Seems to be necessary to push beyond 1/2 MOA and is MUCH cheaper to shoot my precision rifle's caliber: .22-250 Remington, if using reloads.

Glad to see some reloading stuff on Thingiverse already, but to my surprise there was no powder funnel! The "universal" one that came with my RCBS Rock Chucker kit has too much slop to get all the powder in the case when used with haste (who doesn't want to reload faster). Looks like it would work great for .30 cal, but not so much for my less common cartridge. Well time to design a better suited one while eating pizza bagels before getting back to researchy stuff.

This funnel is designed to attach to the neck of either a 5.56/.223 or .22-250 Remington case. With it's FDM compatible foot on the rim of the bowl, and minimalistic nozzle with chamfer, this funnel is easy and cheap to print in any material, AND is still smooth to use despite it's tight tolerances. It's the last 3D printed powder funnel you'll ever need. Download and Make to improve reloading efficiency today!

Note:
"Common cartridge" (.223 and .308 dia) version coming soon. But I currently don't reload any .30 cal so don't hold your breath.

Also I have included images of my parameter names at the end in case someone proficient in OpenSCAD wants to port this to OpenSCAD so we can have a Customizer powder funnel.

Changelog:
V1.1: set neckThickness = .8 mm instead of the actual .3-.4 to help with fitting too tightly.
