Irrigation ring 200mm side inlet.

Remix of the ring by micromet. The generated file is a 200mm ring with half the holes of the original as it is twice the size. Added another tab and moved em to new positions. Moved the inlet port to the side so that its in a better orientation for printing. Its a 5mm barb so should fit 4mm id hose (like the ones usually used for drippers) I printed it with plate supports only for the barb.
