The file 'Woodworking Angle Meter (Remix) 3D Printer Model' is (stl) file type, size is 125.6KB.
I removed the braces, shorted the flap, and put a gap that you can see in the middle. Now, if you need to make a degree cut on a piece of wood, you can put down this over the mark you have, then use the device to mark your selected angle for later cutting
I printed this top side down, just as it is in the STL file
