This is a remix of @fulcrum_design_company 's beautiful Lockset Installation Jig.
The original design was only made for an exterior doors width. I tweaked it to fit a standard 1 3/8" Interior door. Both .stl files are included.
From the original thingi:
This is a lockset installation jig very similar to what you can buy from Dewalt. It's designed for a 2-3/8" backset and gives you the exact location of the holes to drill. It also has a small indicator window to line up the correct height of the jig to your pencil mark. The top can be clamped with a quick-clamp type bar clamp.
