Grass Protection Ring for Rotary Sprinkler Head - Remixed with partial parametric dimensions

Prevents Grass from growing over your sprinkler head by adding a gap between your soil/grass and sprinkler head.

Features

• Parameters to allow changing the depth of the central column as well as the inner radius of the column.  Please note, this is a radius, so if your sprinkler head is 50mm, set the radius to half of that/25mm.
• Promotes smooth operation of your rotary head.
• Can extend down to the earth to prevent lifting
• The included STL is designed to fit around standard 2.75" (70mm) rotary heads. This can be changed using parameters in the Fusion 360 file.
• Works with Orbit, Hunter, Rainbird & Toro, possibly others.
• Ribs on side dig into soil and provide strong rigidity.
• Easy to install
• Actually prints easily in 1 piece.
• Small enough So More Than One Can Be Printed at A Time on Most 3d printers
• Much cheaper than cement sprinkler donuts
• Economical to print. Only about $1.50 each in filament.
• Make as many as you want!
• Print with a 55mm inner radius to fit over a standard Water Main Valve (should roughly match jimerb's https://www.printables.com/model/262535-water-main-valve-grass-protection-ring)

TIP: I like to give the sides of the rotary sprinkler a spray with silicone while it's in use. I find it makes it even smoother.

HOW TO REPAIR A SPRINKLER HEAD USING THE 3D PRINTED SLEEVE (Not my video, from jimerb's original post):

Print Settings

Rafts:

Not needed

Supports: 

Not needed

Resolution:

0.20

Infill: 

13%

Filament: Printed in PETG but use what you want.  PETG/ABS/ASA would be better than PLA as the print will be left outside and is less likely to warp over time.

Notes:

I also added a parameter to change how far the rim rotates around the central column, but it needs a lot more work.  As you can see in the 7th image, it doesn't quite look right.  I did not make the rim parametric, partly out of laziness, but you should be able to edit the first sketch if you want to reshape/size it.

Maybe look at https://www.printables.com/model/194380-landscape-sprinkler-donuts if you need different angled shapes.

Printing Tips

I decided to print this with a faster nozzle size, not caring so much about the appearance.

The ring is going to get covered by dirt and grass so appearance is not that important.

Making the print speed faster makes the slight bevel on top a bit more ragged but that was not a problem for me.
