Cyclops 2 in 1 Carriage System with Chain and BLTouch

thingiverse

I picked up one of the [2 in 1 out Cyclops hotends](https://www.amazon.com/gp/product/B074J7NBPQ/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) to try it out so I designed this. It hasn't been tested yet.... The offset of the BLTouch is 14mm behind the nozzle. Check out my [BLTouch Spacers](https://www.thingiverse.com/thing:3578888) I like the [Mistral 2.1 cooling duct](https://www.thingiverse.com/thing:2121279) and rendered a few images with it. It can use any stock Anet A8 duct and fan. This is meant to use M3x10 self tapping screws to secure the fan shroud to the mount as well as the BLTouch. The new shroud includes a small duct to keep the BLTouch cool. The Cyclops head mounts with M3x30mm screws and captive M3 nuts on the back. It can use any stock Anet A8 fan duct and X belt mount, including the stock method with screws. In your slicer and firmware you need to set up a dual extruder with a single nozzle. The retract on the one I used is 44mm. The BLTouch and [Chain](https://www.thingiverse.com/thing:3461545) are optional but recommended! The cooling duct likes to be printed with support, I printed it with the face the fan mounts to against the bed and excluded support inside the BL Cool duct. - Updated 8/4/19 Changed fan shroud dimensions to fit better the actual extruder I bought, tweaked alignments. - Updated 8/6/19 Updated alignment of fans and parts. Made a clearance for the peak of the extruder I have. This is built around the above linked extruder and fits great. It's in print right now and when done and installed I will upload more pictures and instructions. It's ready for use though! - Update 10/22/19 Been printing with it for the last week just great! Everything stays plenty cool with a super low speed 60x10mm fan on it. The head is lightweight and easy to set up. The BLTouch needs a lot of spacers with my head so I added a small bump to the mount to help. All files updated.
