Better half was looking for a compact and neat way to store many small packets of Diamond Art drills, but in a way that could be easily sorted and easy to see the different colours.

Settled on this design with 3 compartments to prevent the bags from falling over, compartments are sized for 50mm ziplock bags, readily available on amazon/ebay etc.

Interlocking design has a fairly solid fit, with a small tolerance so care to be taken when slotting them together,  currently she has 10 trays printed and interlocked in 2 groups of 5 which seems the most manageable.
