I could not find any mount for both wall and ceiling for my recent purchase, a set of TP-Link Deco P7 mesh WiFi network, so I designed my own.

It also fits the Deco M5 as it has the same outer shape and size.

Update: for those having issues with durability, I uploaded a v2 whith thicker bottom plate and thicker "fingers". I also made the base a little less wide to hide it a bit more.

Edit: Uploaded final version.
Edit text: also fits M5
Edit: added v2

Support is needed for nice clamping hooks.
