Carlon Electrical Box Templates Single & Dual Gang

thingiverse

These templates are quite handy if you need to add outlets to your home or RV. Place the template on the wall, using a small level across the top or bottom to square it up. Use a pencil to mark the wall, then set the template aside. A drywall saw, or an oscillating cutter (my preference) can be used to quickly cut the opening. I printed with an infill of 50% so they'd survive living in a tool box and being transported to job sites. The Fusion 360 files are included if you'd like to modify the designs.
