The Khatt Items Hook Cuff Table Shades make use of laser technology. A laser beam cuts fast and precise through many plastics, Acrylic in particular. The disadantage of using plastics for lampshades is that the material is limited heat resistant.
Thin multiplex wood is another option to use as base material. It is more heat resistant but the lasercuts will color dark brown.

Finally, there is thin (0.5mm) metal. Heat resistance is no longer a consideration but production costs are much higher.

The Hook Cuff Table Shade is a nice informal product that is easy to customise and can be used four or three sided, depending on the amount of panels used.
The three panel version can only be used with thin material. The standard thickness of the material is 3 mm. The 4 sided table shade is 225 mm heigh and has a base of 118 x 118 mm.
