Rostock Max Dual Extruder Mount

Measurements have been slightly modified to compensate shrinking of ABS after printing.
Nozzle delta is X+/- 14mm relative to X0/Y0 of original extruder mounting plate.

Version "V2_mod" aka "old Skully" has X +/- 13mm and greater notches for the heater- and thermistor wires.

Version "V3" aka "crimson hun" has also X +/- 13mm. It includes a cooling solution for the PEEK. I tried it successfully with one single 25x20mm high-power fan. With 25x10mm models, you should use two of them. This version is quiet good to print. I printet it with a .35mm nozzle at .15mm layer height using black ABS.
"V3" requires the "Spacer_New_V3".
Edit: .STL File updated - Slic3r had some issues with the old version.

Version "V4" aka "why-didn't-I-think-about-this-earlier" has the spacers included. This is the Version I actually use here (with two 25x20mm fans). Note: I had to make some changes to the Repetier FW (0.83) in order to use one fan output (FAN2) for cooling the PEEKs, wether heater 1 or heater 2 (or both) is in use.

One issue that will occure is the "swiveling" of the effector plate while moving from the center of the bed to the outer areas. This is no problem with one extruder (centric mounted). With two extruders and the relative delta-x, it is a real challange to get rid of the ever changing Z-alingnment. I minimized this effect by tweaking the "END_EFFECTOR_HORIZONTAL_OFFSET" definition in Repetier's configuration. Just play around with it and watch what happens.

Maybe a "V5" with a 40mm fan mount/duct for cooling PLA prints will follow soon. :-)
