Weed Trimmer Wheel Assembly

I have no idea why my STLs and some of the photos are not rendering. I've tried re-uploading a few times with no luck. If anyone has an idea, please reach out. This is a weed trimmer attachment similar to ones they're selling with new models. Mine, however, is a Black and Decker GrassHog XP that I'm modifying. I also don't like how cheap the wheels are, so I've been thinking about this project for a while. To build it, you'll need 5/16" all-thread (or similar size in mm) and two nuts. I'm including a knob that I melted the nuts into. Cut the 5/16" bolt to four inches long. You'll also need two M3 x 25 screws and nuts. To secure the pins, simply cut a paper clip and bend it on both sides of the pin to hold it in place. You'll need two knobs, pins, washers, and one of each other part. I printed everything with high infill and six wall layers using standard PLA. It might take some effort to work the fork through the clamps, and the all-thread bolt through the fork, wheel, and shield. Don't tighten the nuts too hard or the wheel won't spin. The wheel was just a mock-up and not complete, so it's two parts in one. I planned to design it with bearings, but it works well as is, so I glued the spokes to the wheel and went with it. The shield is necessary if your soil is wet when you trim because the trimmer will throw mud and grass into the wheel and lock it up.
