Washing pump parts - how to get them to dry in 3 hours?

I've rented a Medela lactina (also used the Ameda at the hospital, not
sure which I prefer, both are ok but only Medela was available to
rent).

It's working well, my problem is how the heck I get the parts to dry in
the 3ish hours between use? We're running the a/c in the house so it's
not like it's terribly humid inside, but they just don't air dry!
