This is a coffin shaped Zen Garden with a Mausoleum-shaped tool holder. Details in my Youtube Video.
The entire project fits on 2 12" x12" 1/8 sheets. Make sure the dxf height is 305 mm and everything should be the correct scale.
The Coffin has double walls. The outer ones glue to the edge of the base - glue these first. The inner ones fit nicely on top of the base and flush with their outer partners. The pediment (the entire triangular part at the top) has 3 layers of detail. The tippy top roof is filled with several upside down ‘V’ shapes glued together.
The columns were 3D printed (you can find several styles of columns online)
