Hom3r designed a great model for mounting the Philips Hue Smart Play Light Bar. This is a port for multiboard. You'll see in the pics, im addicted to both multiboard and Hue Play Bar's (have three to light my worksurfaces).

Profile is with 0.6mm nozzle, but have tested with 0.4mm nozzle as well…just change nozzle and choose 0.20 mm standard Bambu profile.

I included both the snap fit and a screw in bolt fit. They are fast prints so try them both and choose the one you like best.
