SummaryNote: Please do not use this design, use the latest Low profile mount http://www.thingiverse.com/thing:887941 This is a direct drive mount for BI 2.5. It's simple for a single extruder. I designed a fan shroud to used with a 30x30mm fan. It can easily by used with a two hot ends (once at a time) but you will need to turn the support. InstructionsYou need to remove the bowden push-fitting and fit the bowden tube directly in the metal cylinder. Print all parts than assemble them: Extend the motor wiring to reach the new position of the motor. Install the EzStruder on the motor. Install the support on the EzStruder. Cut the Bowden tube to 15mm over the aluminium plate. Install the support on the retainer plate with the Center Hole retainer, a #10-24 x 50mm screw, a washer and a nut. The nut goes into the hex hole in the support and the screw with washer in the hole retainer. Install the fan shroud and the supports on the motor support (use small screw, #4 metal screw). The motor wiring goes into the square hole beside the fan hole.
