Individual Nespresso capsule holders hold an entire sleeve of Nespresso capsules. Print as few or as many as you have space to mount. Color coordinate with the sleeves so you always know what you're reaching for.
I mounted these on the side of the fridge with 3M Command strips. Could also easily mount on the side of a cabinet, on a wall, or inside a cabinet door.
Print with thin .10 or .15 layers to prevent layer separation. print with a 5mm brim for best bed adhesion.
Opening has a single wall of support material that you'll need to break away after printing. (Red material shown in drawing)
