Small update: I was really inspired by this model and contest to expand upon my door hanging experience for next go around, and developed a helper model to accompany this one, found here, enjoy:

I saw that the contest was based on drilling tools, and had appropriately just recently needed to mount a doorknob with my drill. I threw together this jig to line up the areas for your hole saw holes and pilots for mounting the latch plate. Went ahead and added some labelling and added a second model with the second type of backset available, and wanted to throw them up as they are a super simple and super easy print that will save you tons of headaches if you happen to be installing a door.
The author marked this model as their own original creation.
