Solar Light 4" PVC post adapter

Needed an adapter for some 3.75" solar lights to fit on my 4" pvc railing posts.
Light is https://www.amazon.com/dp/B091Q1BZDT?psc=1&ref=ppx_yo2ov_dt_b_product_details

It fits nice and snug on both the light and the post. I may print it later in petg if they start to brake down.

I made this quickly with 3d builder and included the original source file if you want to change the dimensions to fit other posts.
