Prusa MK2 MMU Stacking Spool

I ordered a quad upgrade and the spool holder took extra spaces. I designed this so that these spool holders are stacked on top of each other to save space. I have yet to test the printed parts nor the strength of the acrylic frame. I am concerned that it might break but it also should able to withstand about 2.5kg weight.
