dual conduit corner

since we do not have easy access to cheap aluminum extrusion in this size, we're remaking the framework using dual pieces of 1/2" EMT electrical conduit. for each leg.

the inner wall should line up the same as the original cristelia so the upper bearing support should not need to be modified.

This is a first draft and has not been tested yet.
The electrical conduit should go over the corner nubs.
I decided not to add screw holes for attaching the elctrical conduit.
My plan is to print these with a rather heavy infill and at least 6 shells, drill holes through the conduit into the plastic nubs then fill the holes with resin to create somewhat solid mounting points.
