[12/31/25 UPDATE] Addition of a requested Print Profile for a capsule with an outer diameter of about 46mm in the extended height version.  All the other dimensions of the container are the same, including the lids.  Print Profile includes a short capsule for testing fit.

[UPDATE] I have added another Print Profile that is 6mm taller for coins that are a little thicker and to still fit 20 coins in the capsule.

Coin stacking storage for your numismatic collection.  This capsule is sized for to hold twenty (20) 51.5mm diameter/5.5mm thick coin cases (like seen here), commonly used for one ounce silver coins 50mm in diameter or less with appropriate foam gasket.  

Also included are two lids, one looser fitting and one tighter fitting dependent on your printer settings and accuracy.  In my testing, the loose fit will slip on with just enough friction to hold itself in place.  The tight fit will press into place with a snap (edges chamfered to assist in removal).

If other sizes are needed, please let me know and I can make those available.
