Plug
thingiverse
This part is a replacement for a foot pump's plug, locking the pump in its closed position. The original design has been replaced with a flat disk; contact for the former design can be made via email.

Alternatives to Thingiverse are available at http://www.reddit.com/r/3Dprinting/comments/26do2z/alternative_repositories_to_thingiverse/. For printing, I used supports for better finish in overhanging areas with 0.2mm layer height and 20% fill at 80mm/s. The model requires some tweaking to improve strength in reducing cylinders but has worked fine so far.
