filament shelfs

This is a project just something I needed for my printing room. I printed it on my H2D so I could print 12 of the ( 280mm rods ). There are 8 connectors and 4 sizes or rod. The 100mm rods are for the front support to help from tipping forward. 152mm rods go front to back. 216mm are the uprights. ( can also be used as front and back rods can hold 3 spoils per pocket. 280mm are for front and back rods to hold 4 spoils per pocket The pictures I posted was the size I printed for my needs.You can print them in any combination you need. I used M3 X 20 screws. I just used PLA for filament
