Derived from Dan's box lamp:
It is designed to be made with 4.5mm Arctic Ice acrylic and 4.75mm Hardboard.
This design uses two different patterns over the four panels: one a geometric tessellation inspired by tea-leaves, the other a tessellation of typographical forms from the translation of 'tea' into various scripts.
The patterns were scanned from drawings and automatically traced in Illustrator so are unnecessarily complex in terms of paths - if anyone would like to simplify them to reduce the cutting costs, that would be great!
The panels slot together and are meant to be held in friction by small hardboard wedges, however in practice I think this system needs more development - or maybe I got the hardboard thickness wrong. There is currently a lot of wastage on the hardboard sheet, so you might want to consider adding any other items you want cut to that one.
Dan has updated his version of the lamp to include better wedges and incur less wastage on the hardboard. In fact, hardboard is no longer available in NZ Ponoko and is not in 4.75mm in US Ponoko so I suggest using the 4.75mm MDF in NZ Ponoko.
