Rain Bird 51DS Sprinkler Cover

This is a replacement cover for the Rain Bird 51DS sprinkler heads on my friends golf course. The part is no longer available from the company. I printed 2 versions of these, one in PETG with 4 walls and 40% infill and the other with 30% infill. They will be routinely run over with fairway mowers and golf carts, we will see how well they hold up to the abuse. I doubt may others will be needing this item but figured I would share it.
