Bike ring lock mounting system.

My “Cannondale Quick” came without a way to mount a standard bike ring lock, in my case an Axa Defender.

This mount attaches with one m5 bolt to the frame (to a mudguard holder), after which you can mount the ring lock to this printed mount with two more m5 bolts.

Finally I used some zip-ties to attache it to the bars for some extra (needed!) support.

I've included the .f3d file so you can easily make adjustments for it to fit your bike! Definitely room for improvement but it gets me going for now!
