Additional steps may be required to print! (I'm sure the slicer settings could be improved, bottom of shelf layer could be thinner, etc) First design, bare with me. Currently this needed to be scaled to 90% to fit on the bambulab 256x256x256 plate. Adjustments needed:

*remove brim (other>brim type> no brim) *Move object to the back of printer, allowing room for the nozzle purge

Currently testing for a double stack locker shelf. Filament: PLA, 193.61G, cost: $5.81. time @ 100% 5h14m
