Hypercube Titan Aero Mount with DC42 Mini IR & Rear laydown radial fan

thingiverse

1/12/2020*** Added wire support that bolts on back side of X carriage with rear fan mount and extends upwards to support wiring harness for hot end. Has built-in channels for zip ties to go through. Also added New fan modeled after MK3's fan. My previous design limited Y travel from front fan hitting extrusion and my led lights in front of printer, so I remixed Asphyth's amazing mount to work with mini IR sensor from David Crocker. Offset of sensor is 27mm to left of nozzle hole and pcb is 2.385 mm below tip of nozzle (this may vary due to slight slop in bolt holes for clearance so make sure you follow setup guides). Update: Added hole for another heat in brass thread insert to hold fan, re-designed fan to have matching mount. Once installed, I gained 5mm on X axis (due to width of old fan) and 10mm on Y axis. I've included Fusion 360 files as well as STL for my X carriage that uses a 22-pin Molex connector so hotend can be removed easily without unwiring anything, just unplug one plug and it comes off (with rear fan you can add second plug just for that fan so you can leave fan set up on X carriage and just remove hotend). I've also included the cover I made for DC42 Mini IR - this isn't needed but will help keep filament off sensor if there's ever a runaway print. I used tiny Dupont connectors like E3D uses on fans, heater, and thermistor so if I ever have to change one, I can use big plug to get hotend off printer and then simply unplug item I want to swap out and plug in new one.
