modular mini shelf

Modular mini shelf that can be easily assembled using screws and press-fit nuts.
Since I couldn't find anything suitable, I designed this for my kitchen cabinets.

All measurements are in millimeters.

Update 06/2026
added Wall Type B

I printed the walls with this settings:
- PLA
- 0,2mm layer
- 3 walls
- 10% infill

And the boards are printed with:
- PLA
- 0,2mm layer
- 4 walls
- 3 top layers
- 0 bottom layers
- 10% cubic infill

As press-fit nuts I used:
M3x3 outer diameter 4,5mm
