K1 Max Raiser ERCF Mount Hinged Corner

I have remixed this corner of the raiser I'm using on my K1 Max to mount my ERCF filament motion sensor remix.

There may be some inaccuracies in the hole placement, as I have only printed it once and have been using it since then.

The ERCF sensor model itself can be found here: https://www.printables.com/model/1090257-creality-k1-ercf-filament-motion-sensor.
