Water spray heads for my greenhouse. Will fit threaded 1/2" PVC fittings. Six direction flat spray pattern when printed correctly. PLEASE PRINT UPSIDE DOWN for perfect Threads. UPSIDE DOWN means print with the threaded opening UP.
I must give credit where credit is due. The screw base was gleaned from a fitting for a water hose (American thread) on this site. The extension and slotting is mine. Together they make sprayers that are working in my greenhouse right now.
Could not find spray heads at Home Depot to do what I wanted to do. The uploaded 123dx file can be altered for spray patterns, volume, etc. That's YOUR business.
2 STL files presented. One will produce head with 6 holes, one will produce 4 heads with 6 SLOTS.
This .STL file will print you 4 of them simultaneously. WILL PRINT 4 AS IS. I will upload the AutoCAD 123dx file for 1 so that you may alter as you see fit.
The STL file with 4 heads fits 1/2 PVC thread perfectly. However, you might wish to scale whatever sprinkler heads you create with the 123dx files up or down + or - 2% for good fil. You can figure that out.
These can make great replacement heads for lawn sprinklers. No more trips to hardware store. MAKE YOUR OWN.
Must be printed as presented (upside down) for threads and spray holes to be correct. I printed in ABS at 230 degrees C for best results. Raft only. PRINT UPSIDE DOWN!
Took the American thread hose fitting .STL, shrunk to 75% of normal size, saved as .STL, loaded in AutoCAD 123d, created extension with slots, moved into position, saved as 123dx file, exported as you see here, copied and pasted 3 times for 4 nozzles, resaved .STL.
If you can improve it, please do so.
