-Plywood 850 x 350 x 5mm (I used 5mm, but you can use every thickness, just keep in mind that you have to change the length of your bolts as well)
- 180 M3x8mm bolts
- 3d printer
- Sand paper
- Bulb fitting
- bulb +/- 60 watt
Step 1: First: Print All Your Pieces
If you don't want the inner faces you only have to print 4 of the little spacer hooks. This is because of the fitting which has to be attached in the inner face with the hole in the middle. For every inner face you want to use you have print at least 2 spacer hooks.
Step 2: Start Customizing Your Lamp
Use vector editing software to customise the inner faces. I used Adobe illustrator, but there are a few free vector editing programs out there ie.: inkscape
Feel free to experiment, in my experience you won't use all of the inner faces because that will be a bit dark, so you can go extreme just to see if it works. If it doesn't, there are still a lot of inner faces left. But keep in mind that the inner faces must have some kind of frame on the outside to hold the spacer hooks!
Step 3: Lasercut All Wooden Pieces
Step 4: Putting It All Together
Start with a hexagon and screw on 6 corner pieces you printed. Add hexagons and pantagons accordingly (3 hexagons and 3 pantagons). Make 2 of these shells. Put one aside for the end.
Take the other shell and just keep on screwing on pieces, this will take some time. When every piece is used you will only have to attach the shell you put aside and your frame is done.
Now you'll have to put in the faces using the spacer hooks. Start with the one inner face with a hole inside so you'll know what the top will be. Insert the bulb fitting through the hole and attach it at the top.
If everything is to your liking, mount it to the ceiling and turn on the light! Your Lasercut and 3d-printed Truncated Icosahedron lamp-shade is done!
