Philips Hue Dimmer Switch adapter for HPM wall plates.
Use PC screws to attach the Philips mounting bracket to this.
First print it at 100% scaling and adjust
...Plus by 1% if you have issues with it clipping on.
For fancy results, print in ABS and expose it to acetone vapor for a little bit to smooth it off.
I designed this for my HPM XL770 plates. I'm not sure what other switches it will fit but I think they're all pretty similar.
