Filament Rack Frame

I needed a filament storage for my office and none of the ones I found really worked for my situation. I designed this to be modular where you can stack several vertically as well as place them side by side if you have the room. Currently I have stacked 4 high x 32" width with good lateral stability and I am setting on a tile floor. I have included .stl, .step, and .f3d just in case you need to make any adjustments on the fit. I would recommend a test print where you print just the lower and upper sections and make sure they fit before printing a set only to find out my printer tolerances are different than your printer tolerances. Also, please be aware that the interlocking fit between each frame is very tight, it was designed that way and assists in keeping the structure rigid as you go vertical.

Other material used is a 1" chrome shower rod and a 5/8" dowel. I decided on a 32" length to maximize material use as well as avoid any deflection due to filament wei
