The Nexxtender EVcharger does not come with a spool.
This is a 3dprintable spool that fits around the charging station.the nexxtender-haspel-merged.3mf is for previous puposes, not for printingAttached to the wall with screws.
The pictures show a slightly older and larger version, I could provide these models on request.
you'll need a big printbed (300x300x255)!
