5 Genius 3D Prints for Lawn Care Nerds
Download links for five 3D prints that make lawn care easier: a vertical edger for your string trimmer, an Echo RB-60 agitator, sprinkler catch cups, a striper stowaway, and a Toro cup holder upgrade.
The short version
- Came from the TikTok? All five download links are below, plus what each one does and what you need to build it.
- Every design is on MakerWorld. Each one fixes a real annoyance or makes a lawn job more accurate.
- No 3D printer? A friend, a local makerspace, or your public library can usually print them for the cost of filament.
- For parts that live outside or in a hot garage, print in PETG or ASA, not PLA.

1. Perfect vertical edge trimmer accessory
This turns the string trimmer you already own into a wheeled edger, so you get a clean vertical cut along sidewalks and driveways without buying a dedicated edger.
St. Augustine spreads by runners, and those runners love creeping across concrete. Edging is what makes the whole lawn look sharp, and a wheel that holds the trimmer at a steady angle is the difference between a straight line and a wavy one.
What you need:
- A trimmer with a shaft housing about 27 mm in diameter. Measure yours before printing.
- 2 bearings, size 12 × 28 × 8 mm, for the wheel
- 4 M4 × 15 mm screws and 4 M4 nuts
The designer's profile prints in PLA at 0.2 mm layers with 6 walls and 25% infill. It uses about 141 g of filament and takes roughly 5 hours.

2. Echo RB-60 agitator
This is an upgraded agitator for the Echo RB-60 broadcast spreader, built to keep granules moving through the drop hole so the spread stays even.
The RB-60 is a favorite among lawn nerds, but the stock agitator can leave product sitting in the hopper, especially at the end of a load. Uneven flow means uneven fertilizer, and on St. Augustine that shows up as green and pale stripes a few weeks later.
Printed versions of this upgrade sell online for $15 to $20. Printing your own costs a fraction of that, and you can print a spare.

3. Sprinkler system catch cups
Catch cups tell you exactly how much water each sprinkler zone puts down, so you can set run times based on numbers instead of guesses.
Most lawns get watered wrong. One zone runs too long and stays soggy, another leaves a dry patch near the edge. St. Augustine that sits wet is an open invitation to fungus, so knowing your real output matters. Professional gauge sets cost a couple hundred dollars. These print for pocket change.
How to run a quick catch cup test:
- Set the cups. Spread 6 to 10 cups across one zone, including near the heads and at the far edges.
- Run the zone. Turn on just that zone for 15 minutes.
- Read and average. Check the water level in each cup and average them.
- Get your rate. Multiply the average by 4 to get inches per hour.
- Repeat and set. Test every zone, then set run times to hit your weekly target.
If some cups are way higher or lower than the rest, check for clogged, tilted, or blocked heads before adjusting the timer. For how much water St. Augustine actually needs, see how to water St. Augustine.

4. Lawn mower striper stowaway
This keeps your striping roller tucked out of the way when you're not using it, so you don't have to pull it off the mower every time.
Stripes are the fastest way to make a lawn look professionally kept, but a striper dragging behind the mower gets in the way when you're backing up, trimming tight corners, or loading the mower. A stowaway position makes it a quick switch instead of a chore.
Check the model page to confirm it fits your mower and striper before you print.

Don't have a striper yet? The Broominator Jr is the one I'd start with, and it's under $100.
5. Toro mower cup holder upgrade
This upgrades the cup holder on a Toro mower so it holds a real drink, not just a small can.
It's the least technical print on the list and probably the one you'll appreciate most in August. Mowing a Houston lawn in summer means you need water within reach, and most stock cup holders are too small for an insulated tumbler or sports bottle.
Check the model page for which Toro models it fits.

Printing tips for outdoor parts
- Start with the designer's print profile on MakerWorld.
- Add extra walls on anything that takes force, like the edger wheel mount or the agitator.
- Measure your equipment first. A few millimeters off means a part that won't fit.
