Prusa XL assembly helper

Assembling the Prusa XL is a horrible task - even if bought as “fully assembled”. One of the worst parts is attaching and fastening the Nextruder Docks by misbehaving inaccessible screws on the end of a long Allen key.
This helper gives you a better grip on the provided Allen key and/or lets it be propelled by an electric screwdriver. 

Insert the long Allen key on one end and any long enough (10cm) standard 1/4" bit tool.

Any material, any printer.
