Adapter for Switchbot Lock Pro to allow for use with a Euro Lock cylinder with inbterior thumb turn. You'll need to drill out and adapt the hole on the mounting plate to allow the thumb turn to pass through the plate, unless you have a removable thumbturn (which if you do, you don't need this print anyway…)

To remove the stock insert, you'll need to get at the screw that's holding it onto the spindle. The spring loaded centre plate is removable, you need to get something thin down the edge and prize it away. If you're careful, it should bend but remain undamaged. You should then be able to replace it once you've retrieved the screw you need.
