A mount to Dommia grow lights sold on Amazon. This mount is for mounting onto plastic shelving. Printed with .4mm nozzle at .2mm layer height, no supports needed if you print it laying on its side. Mounts just slide right over the light. Since the lights do not produce very much heat at all I printed these using Hatchbox PLA and after having the lights on for 10 hours, there was not heat transferred to the mounts. 2 mounts needed per light, they just slip over each end.
