Depending on your printer's tolerance you may need a dot of glue for some pieces.
You need to print
4x 30degree_foot
4x 30degree_cap
4x 60degree_foot
4x 60degree_cap
6x 50mm_wall
2x 100mm_wall
1x Tray_Bottom
The 30 degree feet are attached to the 100mm wall segments.
The end sections are 50mm_wall>60degree_foot>50mm_wall>60degree_foot>50mm_wall
Cap pieces are placed on top of feet to cover joints, this is where I would add glue if they feel loose.
The tray bottom falls into place and can be glued in for more stability.
