Step 1: Start on the top plane and make a square and when you boos extrude it you can actually choose the angle you want on it Step 2: you'll create a plane by using the reference geometries tool and place it right on top of the boss extruded part in step 1 and then you'll mirror the entire part from step 1 Step 3: now you'll cut a hole using a circle through the top all the way through the partStep 4: Go to the top plane again and you'll make a square in a corner and cut it all the way throughstep 5: now you can fillet the middle outside portion where the two boss extrudes meet in the plane you createdStep 6: now go back too the top plane and go to the mirrored boss and create a circle from the middle axis and cut accordingly and mirror too the other sideStep 7: go to the same surface that you went too for step 6 and use the offset entities tool and you'll have too close off the ends and trim away and excess and boss extrude accordinglyStep 8: now on the same surface you'll create a circular but make it a construction circle make a slot in a corner make the circle and slot coincident and put in your proper dimensions and cut Step 9: now from the cut yo made from step 8 you'll use the circular pattern and use that accordingly
