Blower Mount for Bowden Feed Hexagon Hotend V1.0

thingiverse

Here is a mount I created to attach a hexagon hot end (http://www.amazon.com/gp/product/B00W8FL5BS?psc=1&redirect=true&ref_=oh_aui_detailpage_o09_s00) to a HE3D (http://www.thingiverse.com/thing:919038) x-carriage. I later found out that the HE3D x-carriage is derived from the Prusa i3 Rework, http://www.thingiverse.com/thing:119616, but has two distinct differences - only two holes, .91 inches apart in the middle, and a unique configuration. Recently, I remixed a modern version with an innovative design to be compatible with that hole spacing (http://www.thingiverse.com/thing:1133926). This is my second attempt at designing this part. My initial version, version 0.0, used two 40mm axial fans but unfortunately failed to deliver a satisfactory airflow experience. Consequently, I ordered some blowers from Digikey and, although not satisfied initially, hooked up the 24V blowers and instantly noticed an incredible improvement in airflow behind the hexagon heat sink. From a financial perspective, it appears that using these blowers will have a minimal cost difference compared to my initial design. The 24V blowers efficiently keep the cold end at a consistent temperature but produce noticeable noise. This can be effectively masked by positioning them behind a door. I have included links to the blowers used - Dikey Part#: 603-1116-ND (https://www.digikey.com/product-detail/en/BFB0524HH/603-1116-ND/1014447). Parts used for this design: * 3D printed components: + Blower_Shrowd_Hot_End_Tip + Mounting_Bracket_Left + Mounting_Bracket_Right + X-Carrriage_Mounting_Brackeet + Securing_Plate * In-Production Parts: + 2x BFB51x515MM (Blower Fans - Digikey) + 10x M4 Nuts + 10x M4 Washers + 4x M4 x 25mm Socket Head Cap Screw + 2x M4 x 16mm Socket Head Cap Screw + 4x M4 x 10mm Socket Head Cap Screw The hexagon model used in this project was obtained from GrabCad (https://grabcad.com/library/hexagon-hotend-1). Special thanks to Joseph Rafferty for uploading that resource. I also encountered issues with the axial fan version of this part but managed to resolve them after incorporating blowers into my design.
