This is a laser cut lamp, built with 6mm plywood and an IKEA Hemma lamp holder.
Assembled with wood glue.

If you want a design with different thickness or a different amount of sidepieces, let me know and I will add them in the files list.

BOM for one lamp:
1x IKEA Hemma
1x 1 - Cable centering plate.dxf
1x 2 - Top plate.dxf
1x 3 - Ring 1.dxf
1x 4 - Mounting plate.dxf
1x 5 - Ring 2.dxf
12x 6 - Sidepiece (12x).dxf

Tip: the lamp holder doesn't fit through the top holes of the lamp, so make sure to insert the cable terminal from the bottom first.
