Free standing pipette rack (5x pipettes)

This is a remix on my previous free-standing pipette rack, which makes use of the slightly larger bed of our lab's new Bambu A1 printer to allow printing a rack that can now hold five pipettes, without the need to angle them. The idea is that it's a cheap and easy way to hang pipettes in an area like a hood.

Note that the leftmost pipette bracket is intentionally a tiny bit wider than the rest, to accommodate the occasional chunkier pipette in rotation (like our old model Eppendorf in the picture).

Also note that (as with that original 4x pipette model), the individual pipette brackets are based on a design from the Derisi lab single pipette rack..
