Summary I designed this box after the boxes we use for Western Blots at the lab. I am currently in the process of testing how the PLA fares against the different buffers and chemicals. This box can also be used to store things. Print Settings Printer: Monoprice Maker Select (Prusa i3) Rafts: No Supports: Yes Resolution: 0.2 Infill: 100% Notes: Make sure to print at 100% infill to avoid any leaks into the print itself and to make sure the hinges are solid. You will need to sand the male part of the hinge (the lid) quite a bit for it to fit. Once it does fit, it is pretty sturdy.
