I like this concept, and would favor pooling money for such resources and also explaining the need for such resources as one of the ways to ask for donations to the space.
I've heard interest in both a filament extruder project and in a acetone vapor chamber project during my open hours. I can't really provide more detail though, since it is not my area (I work more in software). But I'll cheer-lead and throw some money in the pot!
