Description
Just like many of you, I bought the "Scotts® Turf Builder® EdgeGuard® Mini Broadcast Spreader" and ended up with stripes in my yard because the fertilizer gets trapped in the wheels. I looked for solutions that varied from taping the inside of the wheels to people with 3D models that modify the spreader.
Taping would be the easiest way, but it looks bad and tape will eventually break off. The other 3D models that solve this problem feel overcomplicated and require taking the spreader apart. None of these seem like the best answer to me so I created my own take.
Since the problem is that the granules are not making it over the wheel and then getting trapped in the wheel where it builds up and then dumps an over-abundance, I figure a simple shield is all that is needed. It's the same results as taping or putting foam in the wheels.
You'll need to print out two of them for each side, the piece works for both sides. There is an up arrow to let you know where the top is, it sits flush with the bucket round bottom, but feel free to move it where you think it works best. I used superglue to hold it on and after trying it out, it seems to hold fine. The right shield (if looking from the front) on mine rubs the wheel a little bit. You can bend the plastic a little or move the piece on the other side closer to the spreader discharge area.
I suggest printing in PETG as it will hold up better to the abuse and is more chemical resistant than other filaments.
