I wanted a small, portable funnel I could throw in a little bag with my PAX 3. I went through many iterations and landed on this.
There are two versions: Regular and Magnets
Just print as-oriented without supports. I recommend printing the funnel and tamper separately.
REGULAR VERSION:
The regular version doesn't require any post processing. Everything just friction-fits together.
MAGNETS VERSION:
The Magnet version just requires four 3x2mm magnets to be glued in. The magnet version is glorious to use. Everything clicks/snaps securely in and out of place. So satisfying.
