Switchbot euro cylinder thumb turn adaptor (APECS)

This is an adaptor for the switchbot lock ultra (may work with aqara and nuki too but not tested) - it works with APECS euro cylinders with thumb turns (chosen as they are very secure). The open end is required as the thumb turn has a safety mechanism that allows for it to be used if the outside is damaged. I have added wings for stability and a stepped brim so it can fit into the mounting plate provided by switchbot and to give it some more stength around the weakest point (where the grub screws go). If you want one without the wings let me know and ill provide you with this. I'd recommend PETG for this. For the screws, I inserted them into the printed part when still warm to create a path as Im not good enough with 3d modelling yet to create anything beyond holes!
