Owon XDM1041 multimeter shelf mount

I have a Owon XDM1041 digital multimeter which I use every day in my home electronics workshop. Once I've decided to remove it from my working table to have some more space for different PCBs and devices, so the best place I've found is a bottom surface of shelf which is fixed to the wall above my PC display. Half an hour in a CAD software, few hours of 3d printing - and voila! The left and right parts are the same file, but one of them was mirrored in slicer software before printing.
