Newbie question about triangle shape.

Hi,
I'm unexperienced with OnShape and other CAD-programs. I've tried to make a frame, in that there should be a triangle-shaped hole, a triangle shape needs to fit in in an angle. Also it should be possible to rotate the triangle and fit the shape also. I've managed to create the planes in the right angle. But the size of the triangle isn't right. I'm doing something wrong and probably much to difficult. When I 3D print the frame, the triangle shape doesn't fit in. The shape is to big somehow.
It is an equilateral triangle with sides of 12,7mm and a height of 11,3mm, to easy fit it should perhaps be 0,1 or 0,2 bigger think.
You can see what I've created so far here: https://cad.onshape.com/documents/c3ca2ee92cdb8707ecf0c5c9/w/3f9b51d9a96e5db7610f6fd9/e/3ef967bc8f6c7904554af14d
Hope someone will have a look and tells me how to fix this.
Regards,
Erwin

I would say it doesn't fit because your tollerance needs to be bigger. You said your frame should be 12,7mm but you show your triangle with a 13mm side. That should be plenty. Did you measure your 3D printed parts to verify they are coming out over-sized? (probably a dumb question, but i figure I'd ask)
