I did not see a holder for the official Bambu filament swatches that I liked, so I made this one.

Included is 3u and 4u height configurations.

There are 2 ROW and 3 ROW configuration's. I prefer the 2 ROW because its easier to remove the filament swatches and it has exactly 80 slots (vs 81). There are 80 filaments included in the kit.

I print with these settings:

PETG

.20 layer height

12% infill
