I had communicated with Zap in the past and asked whether or not a longer screw driver bit existed which would fit into his 3d printed bit adapter for the P4 and he indicated that a longer bit would hit the pliers. It is true that the longer bit made by Leatherman will hit the pliers but a longer bit can be made from a standard #2 Phillips bit made for a standard electric driver. Using a small milling machine or a belt or rotary sander, one can make such a bit, which will provide considerable more reach. See attached pics.
