A simple rack for organizing Prusa MK3/MK4 print sheets. Each module holds up to four sheets with easy slide-in access.

Features

- Stackable: Print multiple modules and stack them for larger collections

- Wall or under-desk mounting: Screw the rack to the underside of a desk or wall cabinet to save workspace and keep sheets dust-free

- Compact: Minimal footprint — stores sheets vertically so they take up less space

What to Print

Each module consists of two side walls and a base. Stack additional modules by printing more sets.

Print Settings

Compatibility

Designed for standard Prusa MK3/MK4 steel print sheets (254 × 210 mm). May also fit other sheets of similar dimensions — if you test it with a different printer's sheets, let me know in the comments and I'll add it to the compatibility list.
