Motivation
The U-lock mount that comes with the Kryptonite kit isn't very secure – it works best with round tubes, which the Aventon Level.2 doesn't really have.
Therefore, I created this instead, for which you can scavenge parts from the Kryptonite mount to mount the lock to the seat tube.

Rev 7
Tested over about 9 miles, seemed sturdy enough.
Hardware
to clamp the mount to the seat tube
Quantity 3 M5 x 14 mm
Quantity 3 M5 regular nuts or lock nuts
lock interface
Quantity 3 M5 thin jam nuts
Quantity 3 M5x10 mm for the lock interface
to clamp the Kryptonite part to the mount
Quantity one m4 lock nut
Quantity one m4x14 mm socket head cap screw
you will need a Kryptonite part which actually interfaces with the lock
2023-10-21 future improvements
I'm abandoning this project in favor of a better mount for my bike. If I were to continue, I would:
deepen the M4 locknut recess
reinforce the recess – it was bulging out under high torque
consider printing a variant with the lock fully horizontal rather than vertical, & parallel to the midplane of the bike
