Modular system for storing whatever will fit. Print any of the containers and they will slide or snap into the rail with enough tension to maintain the set height. Vertical rail can be used with or without the base. I created the base as a stabilizer and basin in order to catch any rogue parts but the usability doesn't change with or without it. If not using the base, I'd recommend placing the containers at the bottom of each rail in order to prevent tipping.

Update Dec 5, 2025

• Added files for male and female connector so they can be incorporated into your own design. Works both as a rail system and snap-in connection. Very tight snap in connection, but not permanent. May require some rocking to remove if used as a snap-in connector.
• Added round, oval and rectangular containers.
