Bill of materials for box

Materials

• EuroBin 400*300

• Wood or acrylic

• Oil

• M2.5 spacer kit

• M3 spacer kit

• Nuts and bolts

• Cable glands

Tools

• Laser cutter

• 3D printer (optional)

Build

Vector file for lasercutting can be found in the Design folder.

WiggleR comprises a EuroBin for housing soil and worms, topped with a wooden lid to accommodate electronics like the Raspberry Pi.

For increased longevity, you can oil the birch wood with substances such as boiled linseed oil or Danish oil. Apply the oil using a (paper) cloth, ensuring to observe safety instructions, as oils can pose a fire hazard.
