Had a neighbor looking for some holders to mount his solar lights to the fence. Discovered that we could not find any he liked so made one myself. Open to any other ideas to the design. I just made it in SketchUp free real quick one night.
Hole is 1inch~25.4mm in diameter. Countersinks are for just normal 8 gauge wood screws.
Printed mine in ABS and have not had any issues yet.
