Dwarf power socket

At present the power supply to my Dwarf sticks way out the back (vulnerable to getting knocked etc); I’d like to get a right angle adapter to bring it closer to the Dwarf body.
Something along these lines …

There seem to be a plethora of plug sizes and I’ve been unable to find which is the right one for the Dwarf.

Can anyone tell me the plug “spec”?

You’ll find this info on the Wiki
Dwarf User Guide - MOD Wiki

The plug diameter of the power supply must be Φ5.5*2.1*10mm

Thanks @brummer .
My face is red from embarrassment as I read through that resource … my eyes are too old perhaps! x
