Dual i3 Bowden JHead Hotend Mount Remix

Based off my original remix for use with 5mm push fit connectors, I've integrated 2 x M3 holes behind the hot ends. When used with a 24mm X -end carriage, this will center your hot ends on the carriage.

I've added nut-inserts behind the J-Head M3 bolts (holes 1,3,5) so there wouldn't be any interference with the X carriage.

The STL isn't manifold, but I've printed it without issue.

I've also included the SKP in case someone wants to additionally edit this.
