CTC Y axis guide bar brackets

This is a remix and update of (once i find the original i will add the details here) a set of Y axis brackets, I added a set for the outside of the case to reinforce the screw holes a bit as i managed to tighten one of the screws too much and put it just about through the cheapo plywood housing. I have plexi windows and door so needed to put an angle on the outside parts to give clearance to the door when closed.. The inside parts have recessed hex nut holes to hold nyloc nuts and the outside are recessed for the bolt heads to sit snug and flush.
