Creality Ender 3/CR10 mount and fan shroud for Triangelab/Phaetus Dragon Hotend, Orbiter Extruder and BLTouch

thingiverse

Hi everyone, I needed a fan way of mounting my Orbiter Extruder 1.5 to my Creality CR20, and a Trianglelabs dragon hot end, so I made one. (However this will work with any creality ender style printer.) The idea behind this was to make the most compact and lightest way of mounting the orbiter, two fans (one 5015, one 4010/4020), the fan shroud, bltouch and the trianglelabs dragon hotend to the backplate whilst also not having to use supports. The triangle labs hot end is hard mounted with 4 screws so that you can do easy nozzle changes. The shroud is designed so that it won't collide with the frame, end stops, belt tensioner or LED light strip (if you are using these like I am). The weight of the orbiter is centred over the x gantry and will not collide with the top of the frame at the maximum height. I'm using a winsinn 5015 fan and that fits perfectly, but I've noticed there is some variation in exhaust opening on 5015 fans. If your doesn't fit, send me the measurements and I can adjust. This doesn't require supports and takes about 5 hours to print. The part cooling fan is piped through the frame and exits from the right and back directly onto the extruded plastic. You will probably want (although not necessarily need) a short bowden tube from the end of the extruder through the top of the mount to the dragon hotend. This should be printed in PETG or something with a higher temp resistance. PLA will probably also be fine if you don't want to really heat the hotend The shroud itself way about 30 g and with everything added it weighs less than every other commercially available extruder/hotend combo before fans and everything has even been added. Fans are attached with 2x m3 20mm bolts (5015) and 3x m3 15 or 25 mm bolts (4010 or 4020). Orbiter is attached with 2x m3 10mm. Dragon hotend is attached with 4x m2.5 bolts that comes with the hotend. And the bltouch is attached with 2x m2.5 that comes with the bltouch. No nuts are needed BLtouch offsets are x = -42, y = -6, z = about 2mm but always check yourself UPDATE: V1.3 means there is no loss of x or y axis. The exhaust duct has been redesigned so that the air better hits the extruded plastic. This version is quite a bit lighter at 30g, but no longer has a second fan duct. This version is far superior than the previous two, so I have removed the old ones. I may redesign it again, so that it has two ducts either side
