I wanted to distinguish my beer from others, and got sick of trying to find different colors of rubber bands—so I designed this while drinking a beer with my father-in-law.

It should be flexible enough (in PLA, at least) to snap onto a variety of beer bottles, near the top. Snap the marker onto your bottle, then you just have to remember your color for the night!

Print in every filament you have to show off your filaments plus provide a variety of colors for your guests to choose from.

Includes a holder for up to ten rings so you have a place to store them.

Print Settings

I recommend printing at 0.28mm layers, 3 walls, 100% infill. I also use a two-line skirt at 1mm distance to speed things up but still ensure it will print well before starting. 

Your printer may vary, but my Ender 3v2 prints this in 4 minutes.
