Simple Rack

Parts list to be printed：

pillar1.STL x2
pillar2.STL x2
Internal_pillar.STL x2
beam.STL x4
Internal_beam.STL x2
board.STL x16

All parts need about 2kg material(PLA) in total.
I use a 0.4mm nozzle and print at 0.2mm layer thickness. And it seems that using a larger nozzle and a thicker layer is also OK.

Because of the large size of the pillar parts, it is recommended to use raft to prevent curling.
