Print two (or more) and glue in 2 round 6mm x 2mm magnets per mount to hold the light strip (or pretty much anything else that you might have in mind as long as it's not too heavy) if the strip is mounted on aluminum, then glue something ferrous to it so that the magnets have something to grip.
Included step file and parasolid to make it easy to remix.
