Not Re-Inventing the Door Latch...

I am building a door (two actually), for my CR10 enclosure, and so I need to have some sort of door latch.  I had started designing a latching mechanism and then thought, why not use an interior door latch from a Jeep, which is a pretty basic door latch.  When I started poking around on Amazon, I found something possibly better - a door handle from a Toyota 4Runner (and some other vehicles).  It is a bit big. but I think it will work.  I just had to model the handle (roughly) and design a mount for it.  The mount shown above is designed to help me finalize the design, but it works (roughly). The way it works is the stock door handle moves a part which connects to a block (which has a spring in it to allow it to be closed without opening the door handle).  When the door handle is opened, it moves the connector to the right, which pulls the block out of the way and allows the door to be opened.  To close the handle moves the connector to the left which pushes on the sprint loaded block and pushes it into the hole in the door sill which latches the door closed.  It is a bit thick, but I don't think it will be too ugly looking.
