This model is especially for storing Hama Midi perler beads. A container fits a 1000pcs pack easily. There's a slot inside the model where you can pop a single bead so you can see the color from the outside without removing the lid. (as long as you print with transparent filament). The containers are threaded, so you can twist and store your beds in a nice tower.

I printed this with Sunlu Transparent PLA, and it came out really strong.

• 5% triangle infill (though i think you can get away with 0%)
• 0.16 layer height
• 0.4 line width (1.2mm thick walls, 8 bottom/top layers)

You need to print 1 Top and as many Addon boxes you need. The Base is only needed if you want a cleaner look. For functionality you only need the Addon boxes and Tops.
