This is a slot-together design. This was built to fit our .040" Aluminum. You may use this design on other materials, you'll just need to adjust the slots. For .040" Aluminum, I made my slots .045". I would advise using this design on materials .125" thick and under.
As always, before you add this to your sheet go through the normal pre-flight checklist:
My file is built at a 1:1 scale
All my type is outlined
I have no open contours
Reversed type has bridges
I have cleaned up all stray points, empty objects and text areas
All my objects are on the same layer
All holes and cutouts are at least 1.5x material thickness
No feature or detail is smaller than 0.010"
