Perfect stand/holder for Keurig "My K-Cup" refillable coffee filter cartridges. It even fits the pre-filled K-Cup insert in my Keurig Duo machine (you have to take it out to fit the My K-Cup refillable cartridge).
Stand is great for filling the cartridges, too, so you don't get coffee grounds all inside your machine.
The triangular cutouts save on filament and let you insert your finger to push the cartridge up out of the seating when the cover isn't on it.
Be sure to turn it upside down and it will print just fine without supports!
Here's a link to the Keurig "My K-Cup" refillable filter cartridge FYI.
Also, be sure not to miss my modular mug riser pictured in the last photo.
Low infill saves on filament for this higher-volume build, and is perfectly adequate.
TURN IT UPSIDE DOWN and you can print without supports.
