Openbeam double beam mounting plate for printable open rail

EDITED: some of the holes were off a little. and the screw holes are really tight as well.
This is going to be how the axis on the BotBQ will be working. The rails are from Propsfactory on Thingiverse, but had to be modified to 15mm size for Openbeam, but the vwheels are the same size. I created the mounting plate in TinkerCAD and have published it to Thingiverse as well (links below). The bearings are 624zz size and I use two of them on the bracket. The mounting plate still needs some work, but I will update it on thingiverse as improvements are made. Its best to get the bearings in the vwheels as soon as they are done printing as it is easier to put them in there when they are still a little warm.
