Perhaps some of you would find this interesting. Last month, while waiting for my first MrSnuff order, I threw together a simple tap box model in Fusion 360. This design has a small pea sized chamber near the top under the sliding lid. With a quick flick of the wrist the chamber is filled with the same amount of snuff every time. This makes it easy to use even in the dark, you always know how much taps out into your boxcar.
This picture shows a couple versions printed in multiple sizes, and one fresh still on the build plate.
