Latch pin
thingiverse
In the Thingiverse design at http://www.thingiverse.com/thing:4592, I swapped out the stock latch pin with this improved part for enhanced functionality. Additionally, I plan to make the top spring-loaded for easy opening, although I have yet to allocate time for that modification.
