I've bought numerous solar yard lights and other things that need to be staked into the ground – invariably, the ground stake is cheap junk and breaks. I'll need a replacement for the broken stake, or just a more durable stake.
This one seems to be more durable than any I've used so far. Printed with ABS filament, 3 wall loops, 20% Infill, and a Rectilinear infill pattern. The stake comes pre-tapped for a 1 ½" ¼-20 bolt that fits thru the connector. Connector sits on top of the stake and the connecting bolt is turned into the stake to secure it. Then the connector is inserted into the mast (rod) of your solar light.
The connector fits into a mast/rod whose diameter is approx. 1 1/8" ID. I can model and upload connectors with different diameters by request.
See attached pictures.
