bycycle or trycycle License plates and frame and bracket

thingiverse

I designed this for my Kaz adult trike. There's another company selling adult trikes now, with plates that are 3x6, the standard size for most bike plates. The frame should fit custom plates from eBay. The hole pattern is from one source, but I'm not sure if it's correct for all. A good drill can fix any issues. It seems there's no single standard bike plate size. If you know what that is, please let me know so I can adjust the hole pattern to match. So far, I've found five different hole and size patterns claiming to be standard. Apparently, nobody makes bike brackets or frames for bike plates. I also made the bike seat post frame bracket for a standard bike. The plates are designed for Montana but will work in any state. They come with blank plates and blank plates with borders so you can make your own plate.
