First-Surface Drain

This is a bulkhead fitting I designed to add drains to a series of buckets/troughs. It is designed to attach lengths of (garden) hose to the outlet barbs.
.
The drain can fit through a 3/4 to 1 inch hole through any flat container wall up to 1 inch thick. (Swimming pools, barrels, ponds, fish tanks, or whatever you've got.)
.
The drain is what I call "first surface" (more on that in the instructions tab) which basically means it looks interesting and is printable without additional supports.
