Onyx RCR license plate bracket

This is a license plate frame that mounts to the Onyx RCR motorbike underneath the seat. There are unused bolt holes where the seat mounts that you can use to attach it. The angle of the license plate is adjustable, though you'll want to keep it slanted so that the wheel doesn't hit it when you go over bumps.

You will need:

• 6x ¼"-20 machine screws or bolts, 1" long (or M6 equivalent)
• 6x Nylon-insert ¼"-20 locking nuts (or M6 equivalent)

It's very important to use nylon-insert nuts or threadlocker to avoid the plate coming loose from vibration while riding. If you don't do this, it's only a matter of time before your license plate falls off in the middle of the road. Trust me, I've had that happen. 

Both parts print without support.  I recommend using PETG or ABS/ASA and using relatively high infill - though admittedly I printed mine in PLA and it worked just fine for a year.
