Socket Box for Xiaomi Aquara switch

Standard european round socket boxes are too small to fit Xiaomi Aquara switch. It is possible to order [special 'chineese size' 86mm boxes](https://www.ebay.com/sch/i.html?_odkw=power+box+86&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xsocket+box+86.TRS0&_nkw=socket+box+86&_sacat=0) on ebay, but they require too big hole and hard to mount accurately into existing interior.

So I designed something in between - big enough to fit Xiaomi Aquara switch, but not as big as 86mm boxe
