This is a mount for the Govee Permanent Outdoor lights, non-pro model (H705 series). You'll need 12 mounts per strand of lights, or abotu 108 for a full 150 foot kit. These do require printing with support, and I have two profiles, one for standard supports, and one for supports with a PLA interface (AMS) to make it super clean/easy to pop the supports off. These brackets can easily fit on a 1x2" or any 2x4, 2x6, etc style lumber due to the offset screw hole mounts. Holes are sized to fit a #8 screw (about 4.5mm). This design covers most of the light including at the top for the most support possible.
