UK Handle Mounting Plate for Aqara U200 Smart Lock

The Aqara U200 Smart lock is designed to be mounted to locks that are mostly flush to the door, which isn't the case for many UK homes. This model aims to provide a backplate for the U200 that fits around a UK handle and thus allows the lock to be mounted with adhesive for a much more solid installation. 

I have mounted mine using double sided Sellotape and seems to be holding strong. 

I've included the step file to the model with adjustable parameters for Handle Width, height from top of lock to bottom of handle, Handle depth, as well as height and width of the smart lock if you want to use this with a similarly designed smart lock. 

This is my first model posted here so please let me know what you think!
