Geocoin Storage Box With Lid

A simple, long rectangular storage box designed specifically for geocoins and coin holders.

This design was created to accommodate larger geocoins, including those stored in cardboard sleeves or plastic coin holders. I couldn’t find an off-the-shelf option that suited my needs, so I designed this box to better organize and protect my collection.

The current sizing holds approximately 35–40 geocoins, depending on thickness, when stored in dual plastic sleeves. It can accommodate plastic sleeves measuring up to 2.75" in size. The reinforced lid design also allows multiple boxes to be stacked securely for convenient storage and organization.

For added strength and durability, I recommend printing in PETG.

Personal print settings: I updated the wall loops from 2 to 4 and added an outer brim with an 8 mm width and a 0.3 mm brim-to-object gap to help with warping.
