Summary

The design has been updated with a rounded case with a better fit!!

for the updated design print the case with the outside down, it keeps the inner mechanism smoother and will prevent jamming.

--This is a spring loaded double action switchblade mechanism, it opens and closes from the same switch.

--It may require some wiggling to get everything into place but it all fits.
--The latch requires some adjustments (bending) after installed to prevent it from jamming or stopping it before it latches open/close.

--in the future there will be version that uses a real house key.
