I was using a lightbar with my Prusa MK3S+ but when I added the MMU2S the light no longer worked as it was. I already stuck the light to the light ring so I didn't want to remove it, so I printed an angle bracket to still be able to use the light ring as is and still having full access to the MMU2S. This is modeled with an interference fit, if your printer is dialed in it will be snug.
Made to fit this lightbar
