I designed this part to make swapping hotends on my P1S faster, easier and especially more reliable.
Particulary in poor lighting conditions this cable guide makes it much easier to connect the wires of the hotend to the toolhead.
To install the part, simply remove the front cover of the toolhead and unplug the cables. The guide can then be slid over the connectors.
Note: The printer should be turned off when swapping hotends.
