Cerambot delta printer 65° fixup wedges

My Cerambot 3D printer came with 65° prism posts (vertical aluminium extrusions) instead of 60° ones, preventing correct assembly.

These wedges allow to correct somewhat the angle. These are 2.5° so using six of them at the top and six of them at the bottom "removes" 6x2.5° = 15°, allowing to make a triangle.

This is not a perfect solution as the resulting triangle is a bit larger than what it should have been had the posts the correct angle. The main consequence is that the top and bottom
