I really liked the Planet Unknown Locked Tech by canadiankorean and came up with this extremely simple storage solution. The two solids are supposed to be printed in vase/spiralize mode and will fit in the original component tray that came with the game as can be seen in the pictures above.

Tip: If you set the line width in your slicer to something wider than your actual nozzle size the prints will be sturdier. I use a 0.4mm nozzle and set the line width in Cura to 0.6mm.
