Scooter fender

thingiverse

This fender fits a Razor E300 scooter (w/ 9 inch tires). Winter rain is coming and all the electrical is in front, on the bottom of the scooter. There's no weather protection. Even the manufacturer instructs: "Do not operate this scooter in wet weather." So a fender is called for. The original plan was a long all-plastic fender. A bike person told me if I go over a curb, I'll likely hit the end and break the fender. So I cut a couple inches off the tail and added a flexible, rubber mud-guard. Sometimes they use leather, or just a piece of soft plastic from a milk carton. Anything will do... Attach it however is appropriate. The whole fender STL is included. It might fit on a 8x8" bed. I had to chop it in half to fit my 5.5" print bed. Those half-files STLs are included. The scooter has no provisions to add fenders. There's not a lot of room to drill and tap holes. I didn't even have any suitable metal to make stays. So I figured why not just print the fender-stays. The filament I use is very strong and flexible. It worked out well. These just slip over the wheel's lug nuts. It's only a sidewalk scooter. They'll probably last for ever... Wherever things were joined together I welded it (the mud guard is bolted on). I used a 3D Pen to add melted plastic to the joint, and then smoothed and worked things out with a hot knife blade (use a soldering iron, wood burning tool, or whatever is available). Welds are very strong if done right. The fender's top plug fits into the fork tube. I attached the plug and spacer to the fender, and then just hot-melt glued the assembly into the fork. Fast, easy and strong enough... I'm particular about things, and was hesitant to build it this way, but after seeing the finished product I'm very satisfied. If things need changing down the road, they'll get changed. There will likely be some minor surgery required, depending on how you like things to be, or how they'll need to be to fit your scooter. For example, the fender could be closer to, or farther away from the tire. Don't be afraid to trim or modify pieces where necessary.
