The file 'Adapter Bracket For Ring/Cafe Lock On UK Boardman Adv 8.9 Bike 3D Printer Model' is (step,stl) file type, size is 794.7KB.
This is an adapter allowing a dutch style ring lock to be attached to a UK bike with mounting points on the rear fork. I really like this style of lock which is really quick to lock and unlock, very minimalist, and just stops the back wheel from spinning so nobody can ride your bike off while you get off to buy a coffee. (They could still throw it in the back of a van - this is just a quick solution for short stops within sight of the bike.) Normally UK bikes don't seem to have mountings for them but this print resolves that with 7 m5 bolts and 4 nuts.
I have the Boardman Adv 8.9 and the Kryptonite ring lock, but other bikes and locks with the same dimensions would also work.
Please note the printed part doesn't form any part of the lock's security, it just fixes the lock to the frame. If someone broke or unscrewed the print while it was locked there would still be a thick steel ring preventing your back wheel from spinning.
