Filament Efficient Folder Holder (requires cardboard)

thingiverse

A teacher in our school had a storage cabinet that was used to hold folders, but the width was too thin to fit even a simple manila folder. From this point on, my engineering class became a makeshift IKEA, and stayed this way pretty much all year. This storage solution is designed to use a reasonable amount of filament without losing structural integrity. We accomplished that feat by stealing all the cardboard boxes from the copier rooms. We cut and super glued the cardboard onto a frame in each shelf. Using frames with cardboard on top allowed us to tenth the filament usage. This was not our only issue though. Our shelves needed to fit these parameters: ~Large Generic folder is 24 centimeters so width of slots need to be >24cm. (26cm of room and walls are 1cm on each side Total:28cm) ~10 slots for folders ~Height of each slot is 4cm (y-axis) ~Length of generic folder is ~31cm ~Horizontal orientation ~87cm wide is how much horizontal distance we have (x-axis) ~31cm z-axis ~Each slot needs room for a label The biggest issue was the size of the shelves. Our 3D printers could not fit a shelf of this size on the build plate. I was persistent and denied any simple solution to the problem, so my partner and I designed a complex set of interlocking mechanisms all in the spirit of saving a teacher down the hall from enduring the intense suffering that goes along with slightly too small folder spaces for your student's work.
