Sprinkler Head Extension

This is an extension for Rainbird and Hunter sprinkler heads. They sell 6in long ones, but not anything between. There are a 1.5in and 2.0in extensions included here.

These allow you to get the water above the grass where it is tall or the head has sunk into the ground and you don't want to dig it up and reset it.

I have tested this design to 80psi.

If you appreciate my designs a small tip helps me make more of them.

Print Settings

Printer Brand:

Creality

Printer:

Ender 3

Rafts:

No

Supports:

Yes

Resolution:

.08 progressive to .2

Infill:

3 walls, 30% triangle

Filament: Overture PETG clear

Notes:

The threads need very fine layers to work properly so I set them at .08mm and they came out quite good. The main body however would take a long time to print at that layer height. So I set the body to .20 layers. Each part then takes about 1.5hrs.

Print them with the male thread on the table so that you don't have supports on the internal threads.

Post-Printing

Thread Cleanup

After printing and removing supports, you will need to work the threads into a mating part back and forth to rub off any rough spots. Vigorously blow the dust that forms off frequently as it causes it to bind.
