Pipet tip box shelves

thingiverse

These pipet tip box shelves have taken off in our department, with lab rats going crazy about how they keep the hood organized and free up surface space. Safety inspectors also appreciate how they boost laminar flow by moving tips away from vents at the back of the hood. We've got a few different variants that differ based on some aesthetic elements and slight dimensional differences because different companies' boxes come in different sizes, but most are close enough to work with. If needed, scale them up or down in your slicer before printing. When they're done, mount them in the hood using 3M command strips. Give the surface a good scrub with ethanol, acetone, and a scouring pad for optimal results, and use at least four strips. These have fallen down when not attached properly, but if secured correctly will stay put. Thanks to Michael Ramos for coming up with the original idea.
