Waterfall Spreader

Update 5/31/2025: I added the openscad source file 34_GHT_To_WaterFallSpreader_Rev1.scad if you want to create a different adapter fitting than the one I included or add or subtract a little thread tolerance.  You will need to download the file: OpenSCAD threads to include with my source code to generate the thread portion of my model.

Waterfall Spreader to use with a pond pump & 1" ID Pond Tubing.  I used a 280 GPH Pond pump by Pond Boss I purchased from Home Depot.  I included an adapter model that connects to the flow control adapter on the pump and 1" tapered threads to connect to the 1" ID tubing.  There are 2 versions on the spreader.  I used the one with the 90 degree bend to keep from having to bend the tubing more, but both should give you the same water flow.  I choked the inner outlets down which gives the water flow more even across all the outlets.  The waterfall Spreader is 178mm wide so it should fit on a 180mm build plate.  I used the Blue PTFE Thread Tape on the threads to give a tighter fit.
