Cutting guide or tool for circular saw at 45 or 90 angle

Cutting guide or tool for circular saw at 45 or 90 angle. Whole triangle is 200x200mm and a guide along one edge (you can pick left or right) to catch it along an edge. There are two hexagonal holes to insert nuts. Last model file is a clamp which you you print along in one go on the same bed with two vertical slots. You can then use wing (butterfly) nuts to fasten the clamp to bottom side of a wooden plank (max 30mm), so you don't have to hold the triangle while cutting with your saw.

Model can be scaled, flipped or mirrored to fit your needs however with the left and right versions you should not need to.
