5-sided Grill Lantern
The design of the side panels is pretty interchangeable. I could think of bubble or leaf pattern like on my trivets, as well as some stars, hearts or any other geometrical forms you like.
My build was done on a desktop cnc-machine by Stepcraft 420 using a spiral-toothed 1.2 mm flute. I used 6 mm Baltic birch plywood for the horizontal parts and 4 mm pine for the panels. Because the side panels are so thin I made a chamfer on a disc sander. The parts went together without any glue. A coat of oil intensified the wood structure and color.
A word of warning to the usage of a fine cutter on pine: the wood resin gums up with the milling dust so badly, it's a real pain to clean it out afterward.
