About this 3D model

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. Video of installed item can be seen here - https://www.youtube.com/watch?v=n2r9XqPwZHA&feature=youtu.be I've also included the SKP in case someone wants to additionally edit this.
