Interior Garage Door Knob

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4457661.

When we moved in there was no way to lock our garage door from the inside. For a couple years we made due with a pair of pliers, but they were too heavy for the mechanism.

This was my prototype, but it works well enough that I'll use it as long as it lasts.
