AXA defender bike dutch lock base plate

I wanted to fit an AXA Defender lock to my bike, but the lock didnt fit flush to my bike frame so I made a plate that sits on the frame to space it out from the gear cable. I built up areas to fit the bike frame. The plate matches the shape of the back of the AXA bike lock.
I exported to a step file for those who want to change things for your frame.
my frame contour looks like the DXF file. I loaded a plane base outline DXF file
