Langmuir Crossfire Pro Controller Shield 20" x 12"
Used to shield the controller cover from sparks. It does require your ability to bend metal - slits are provided in the DXF. I made mine out of 22ga steel and used a HF cheap metal bender.
NOTE: The design has been modified from what you see in the photos. In the photos, you see the keyholes going vertical. This didn't work as the large square pipe nut sticking out prevented this from working as planned.
SheetCam settings:
Slits - no offset
Keyholes - inside offset
Shield - outside offset
