I made this shelf from recycled pallets wood.
The building process:
1. Disassembly pallets.
2. Measure & cut.
4. Painting - clear matte lacquer.
There are six types of different parts. (see in drawing)
Measurements in the drawing are in millimeters.
The connection between the parts with a minimum of tolerance and with little glue.
Only four screws and two mounting brackets needed.
