Modular Spool Rack

I had been storing my filament in sealed storage bins which became frustrating having to dig them out every time I searched for a specific color. I needed a solution particular to my available space but also wanted one I could adapt for other spaces. I came up with this modular rack. It can be stretched or stacked as tall or wide as you like using the included support braces. It was designed for ¾ inch dowel rods. You may want to make a test part prior to printing an entire frame piece. The vertical rods are 196mm which provides a small amount of clearance for a 200mm spool. #6 screws to fasten the frame to the rod. I recommend at least a 20mm or 1" screw length. Mini caster wheels can be installed to the bottom for easy movement as desired. I used these from Amazon. https://www.amazon.com/gp/product/B0BS287L8Q/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 Update 1: Now includes 3MF, STL and STEP files. New taller STL files for the bottom parts to prevent spools from sitting on the ground if not using casters. Update 2: Added stl's with middle parts that now go all the way across eliminating the need for almost all supports. Update 3: Added stl's for a bottom row to hold small spools. Update 4: Added stl's for all parts with triangle rather than honeycomb. Should print upside down and only need supports for the vertical post holes. Assembly Video
