Parkside PWSA12 to Right Angle Die Grinder Mod (Roloc)

I converted a Parkside cordless angle grinder (25€) into a Right Angle Die Grinder.
You have them from Milwaukee, but those are way too expensive (180€).
It consists of a 10mm spacer and a cover plate to make the grinder look nicer.
I bought a Roloc pad on Amazon and sharpened an M5 bolt so that it fits into the pad.
Always wear safety glasses when using this tool. At your own risk, of course.

PLEASE: I am curious, so please post your makes...
