I use a lot of disposable pipettes in my hobbies, especially painting. However it always seem to be a problem putting the pipettes down for a moment and not getting their tips dirty. So I’ve created my little holder here. It holds the pipette until I need it again and keeps the tips clean until then. I like to use a section of a plastic egg carton to line the bottom well to keep it clean. They might be disposable but no need to waste them.

It printed it in two parts and uses two M3x 4mm heat inserts to secure the top to the base.

I've included two versions of the bottom half, one with with holes for wall attachment beveled and one without the bevel. I think the bevel increases the chance of spliting the plastic unless you are very very careful whe you are screwing in the screws.
