This is a modular capsule holder for Dolce Gusto coffee capsules.
Simply print six of the base part and as many stacking parts as you want and slot them together!
I printed it at 0.3mm layer height on a Replicator 2, each part took just under two hours.
There are two files, you will need 6 of the base file and as many of the stacking part as you want.
There are pins and holes that allow it to all be put together with ease.
