Core a8 Corners for 3/4 inch conduit

A while ago, I designed adapters so that 3/4 inch conduit could be used for the frame. I have decided that it would be even more structurally sound, if I just re-printed the corners that will accept the 3/4 inch conduit as standard. In this design, I have also adjusted the pulley mounts so as to give the belts a little more room so that they don't rub on the inside of the conduit.
