Template khuôn all-in-one 45/90/135 độ (Octagon Template)

Templates to easily join boards at a desired angle. Multiple versions are available for different board thickness. You can get away with the thickest one if the desired precision is not excessive, or you can print multiple versions if your board thickness varies.

I used these to make octagonal formwork (135 degrees), but all angles of 45, 90, 135 and technically also 180 degrees are supported.

I tried using woodworking clamps to hold the templates and boards together, and it worked, but realistically for the intended purpose just holding everything tight by hand is enough.
