The original Parthenon box was remixed from a GrabCAD model not meant for 3D printing which meant there were bits too small for printers and the pillars didn't all line up. I used the old models as guides and rebuild it scratch in Fusion 360 with some upgrades:
All of the pillars line up and there are no issues with the mesh on the middle part where the pillar tops meet the ceiling.
Sturdier lid design. Also all internal overhangs are 45 Degrees so you can put the support position to everywhere to help with the overhangs on the front and back reliefs.
3 catches on each side to reduce how much the lid wobbled.
Better tolerances.
ASSEMBLY:
All of the main sections have one continuous hole which helps line up the pieces which need to be glued together. BEFORE gluing the middle section to the base parts slot the catches in and make sure they can move freely (if not sand some faces down and try again).
