Interior Door or Bathroom Replacement Key

Interior Door or Bathroom Key

This is a printable replacement for interior door passageway keys that use a flat end, like you would find on a bathroom or bedroom in the U.S.

We used an FDM printer and printed this with 8 wall loops and 20% Gyroid infill. Our prototype was printed in PLA and works fine given how light the pressure needed to turn the lock is.

You may need to scale this to better match the size of your lock.
