Required materials:

• Wood glue or glue gun for wood, or acrylic glue if you are using acyl.
• 3 mm (1/8 inch) wood or acrylic sheet of your choice.
• Sanding paper. (Grid 160 or higher)
• Power cable.
• E14 socket of your choice.
• Use some latex gloves if you are working with acrylic glue.
• Optional: Switch and/or power plug.

Required tools:

• Screwdriver set.
• Laser cutter. (40w or higher)

Specifications:

• Dimensions: 375mm x375mm x 375mm.
• Faces: 12
• Parts: 163
• Socket: E14
• Number of vertices: 20
• Number of faces: 12
• Number of edges: 30

First we need to cut all the required parts in the laser cutter.

We us Visicut at our local makerspace to create the gcode for the laser cutter.

I took the liberty to create 3 nested files containing all required parts. They are made for 450mmx600mm 3mm sheet material.

• nested450-600sheet1.dxf
• nested450-600sheet2.dxf
• nested450-600sheet3.dxf

If you have another laser bed size you will need the following files to be cut.

• 150x link.dxf
• 11x side.dxf
• 1x er27.dxf
• 1x top.dxf

Wood: Use some sanding paper with fine grit (160 or higher) to clean up burn marks from the laser cutter. make sure you don't take away to much material.

Acryl: Remove protective foil and clean with soap / water mix if required.

Painting wood: You can use wood paint to give your lamp a color or some protection against the elements.

Don't use oils because it could cause you glue to loosen over time. It is also recommended to use a spray can as the finish will be much more even than using a brush.

The easiest way to assemble the lamp is to create 4 sets of 3 sides. Use some glue to fix the links in the edge of each side. After creating the 4 sets and letting them dry first you can proceed to assemble the hole lamp. Picture above shows one set.

I hope you like the build. Feel free to comment if you have any suggestions. Made in the Walking Robot Makerspace (Belgium Antwerp). Visit http://www.walkingrobot.be for more info.
