MPCNC Mid Spans

I quickly designed and printed these for my MPCNC. I'm running one at 36" x 36" and noticed a tiny amount of sag when the gantry was in the middle of both axes (plural of axis - doesn't look correct to me either).

This design uses (1) 1/4x20 bolt (bolt length dependent on your build height), (2) nuts, and (2) washers. The bolt heads are a tight fit but won't budge once it's in there.
