hole jig guide template for downlights pipes etc

Hole jig for drawing circles up to 408 mm diameter quickly. I got tired of constantly searching for a paint tin, plate or something with the right diameter whenever I had to fit a downlight or put a pipe through the wall and had to cut it by hand or with a jigsaw. I now have one in every toolbox and give them out at work. Holes are marked at 1 mm increments therefore diameter increments of 2 mm. Stick the pin/nail in the hole next to the zero that is directly below the radius you require. Dimensions: 219 mm x 39.3 mm. The thickness of the orange base plate is 1.2 mm. The thickness of the raised black letters is 0.6 mm. To achieve black letters, I cut the filament off at the extruder when the letters started printing and fed in black filament behind the orange. Layer height: 0.2 mm.
