At that point it would be fair to inform those of the users who, after the printer assembly, will continu with the enclosure assembly, that most of the following steps WILL HAVE TO BE UNDONE to integrate the printer into the enclosure! This includs also the attatchment of the power unit to the printer frame.If you are in this case I strongly recommand to read the printer preparation steps described in 'Original Prusa Enclosure Assembly', starting at '2c. Preparing the printer (MK4)'.
it is generally point to the tool itself not the individual end, it is the same for the 2.5 allen key.
