BTWIN 900 Mini lock fix

This is a lock fix for the BTWIN 900 mini lock. Simply slide the lock inside the printed part and gravity will do the rest.
There's little play to allow for the part to easily slide at a cost of very little wiggling.

The outer diameter (that is in direct contact with the bike) is 33.50mm.
This is to be installed in place of the bottle holder. I had to replace the original screws with 2× 6mm M4.

This took about 8h to print. I suggest you to print this in PETG in order to increase the part's lifespan and limit plastic deformation.
