Stackable Freestanding Filament Rack

thingiverse

I created this filament rack inspired by a similar design from uCHobby (Filament Rack Adapter https://www.thingiverse.com/thing:2294603). I wanted a more vertical rack than any online, but couldn't find one that stacked vertically. So, I designed one using Autodesk 123D. By adjusting the conduit lengths, this will create a rack as tall or wide as needed to fit your space. This rack uses 3/4 EMT galvanized steel conduit (a bit overkill, but still cheap). The one pictured is 2.5 feet wide and the vertical support conduit pieces are 9" tall. Although 3/4 inch conduit is 23.4mm OD, I had to design the holes larger (24.0mm) for a good fit. If your 3D printer can reproduce correct sized holes better than mine, you could scale down the print by a few tenths of a percent for a firm fit. I've included a small test block with the same hole size as the rack brace so you can do a test fit before printing a whole brace. Check out my spool holder design, an add-on feature: "Spool Holder for the Stackable Freestanding Filament Rack" (https://www.thingiverse.com/thing:2953103). I extended the top bars over my printer and added a spool holder to get the weight of the spool off the top of my printer and add multiple spools holders above it.
