This is a completely modular storage system based on those plastic stacking drawers available in most homeware shops. 

Each layer of the stack is made up of one frame of either 50mm (1U) or 100mm (2U) and one draw. The drawers are available in 1U or 2U, with or without Gridfinity. Top plate to complete each stack. 

I have tried to maximize the topology of the models for high-speed printing by eliminating any right angles that would necessitate deceleration/acceleration. I have printed them at up to 150 mm/s on an Ender 3 S1 Pro running Klipper without any issues.

Feel free to modify/remix to meet your own needs.

Thank you to Zack Freedman for Gridfinity and the community for some of the other designs that inspired this one.
