Kwikset Door Knob/Handle Extension

thingiverse

I've installed an interior door into my attic space at home and I wanted to add 2 inch rigid foam insulation to the outside to create a better thermal break. The problem was that if I put the foam over the door handle, it would be buried in insulation, and if I put it on the inside of the foam, the door became too thick. So, I designed an extension piece for my Kwikset door lock. It has two components: one will extend the door latch mechanism, and the other will extend the handle turning mechanism. I tried to make this component as strong as possible, but the door it will be used on won't see heavy usage, so I'm not too concerned. If you're looking for more longevity, consider printing or casting in metal.
