This is an under desk holder for the basic model of a cheap chinese smart powerstrip. It's all over aliexpress, banggood and amazon, often just with different brandings, but its all basically the same thing.
The holes are very thick, but I made them to fit the screws I already had lying around. Theyre m5 20mms I think. Theyre honestly an overkill for this, but It works.
I would advise you to flash sonoff tasmota on it. Its pretty hard compared to standard sonoff switches, but its definitely doable. Heres a quick tutorial for that: https://github.com/arendst/Sonoff-Tasmota/wiki/ZEOOTA-Wifi-Smart-Power-Strip-4-EU-outlets-with-4-USB-ports
