Tevo Tarantula Super X Mod

Edit - 3/11/2018 - I remixed the Super X Carriage and ducts to include wider/taller/smoother duct work, a better drag chain receiver link and corrected dual nozzle heat sink mount screw positions. To print these newly revised upgrades, find the 2.0 files. Edit - 3/6/2018 - I made some alterations to the Super X Carriages while also cleaning up the code in the SCAD file some. The fan tunnels now have filleted corners, are wider and with less severe turns which will aid in air movement and because the tunnels are more consistent, less turbulence will be the result. In the process of moving the tunnels around, I was able to free up some room near the front idler wheel hardware. I still have to finalize the bolt on ducting as the previous ones won't fit the 2.0, but I anticipate having those done and ready to upload sometime tomorrow. Edit - 3/3/2018 - The drag chain pin receiver hole (on the Carriage) was still misaligned, but I've corrected it and reprinted the carriage to verify that the chain links up correctly. All is well again! Enjoy. Edit - 3/2/2018 - I updated the Dual and Single nozzle carriages as there were flaws in the drag chain linkup. I'm printing the altered carriage now and will report back if how everything line up, but I'm confident everything will be good and is why I released the updated files before hand. This flaw aside, I am very happy with the functionality and alignment of everything else. Edit - 1/24/2018 - I removed the drag chain links as I've greatly refined the design. The refined links, along with other components will be joined together in a separate collection and I will add a link to that in this description. I've also went ahead and changed out the Super X Motor Block with the updated chain link connectors. Drag Chain Collection - https://www.thingiverse.com/thing:2769475 Edit - Happy New Years!!! - 1/1/2018 - Super X Duct (rev 6). This time I added a BLTouch mount on one of the downspouts and increased the duct openings by another 0.5mm and also increased the downward pitch of the jets as well as the manifold(5º). So between the downward pitch of the jets as well as the increased pitch of the manifold, there's plenty of clearance to blow air only at the print and not on the hot end. Edit - 12/27/2017 - Yet another duct revision (Rev 5). This time I rotated the legs backwards 2º that will in turn force the skirt to rotate forward by that much when mounted which will translate better aim of the air jets towards the print and less on the hot end. Edit - 12/26/2017 - I altered the drag chain link connectors to include a tapered inlet to assist in chain connection and removal. Edit - 12/4/2017 - I refined my drag links by giving the receiving side a slightly wider stance and a bevel on the opening to improve joining and disjoining of links. I also added a custom bridge support that is very easily removed with a needle nose pliers. Just crush both sides of the support and twist and it cleanly pops right out, but if you're more comfortable with your slicer's support structures, there are also STLs with no custom support. I will soon be designing a bed and frame mount to confine the heated bed cables. For best results, print them slow @25mm/s, 0.2 first layer and 0.2 layer height. Once complete, I will be back to finish my control boxes. Edit - 11/27/2017 Thanks to Jim Brown for giving me the measurements for a single extruder heat sink mount, I grafted this in for those with single nozzle kits. Edit - 11/22/2017 I added 2 more revisions to the ducts. Rev 3 gets very close to the bed, but I use bulldog clips to hold my glass and Rev 3 kept getting caught up. Rev 4 backs it off just another mm and clears the bulldog clips. I aimed the air jets down just a tad more on both. Missing parts (Mechanism & Turnwheel) can be found @ this link as my design began as a remix of that Thing. https://www.thingiverse.com/thing:1730521 As of about 10/15/2017, I've been using my own remix of this project which entailed remixing my other designs, so rather than update all of my other remixes, I just put everything I have here. What I did different was to bring the BLTouch outside the carriage and away from the heat block, made the carriage a 3 wheel car, greatly updated the fan ducts that print great and blow as desired. I still want to do some added tests, but I've already printed some stuff and everything came out good. I also added in receivers to run chain links of either side above the belt. I also made very nice drag chain links to hide wires, no hardware needed and absolutely no feeding wires through the links, just a slalom around the keepers which makes the links an open link design. I am also thinking of altering the new ring duct so I can mount the BLTouch from the leg mount screws as the probe can now contact the Z rails which I don't want. My overall intent to have the X car travel as far as possible to ensure each of the nozzles can cover 100% of the bed rather than left nozzle covering from 0-190 and left 10-200 leaving only 10-190 that both nozzles can reach. Up next, a case to hold a Raspberry Pi 3B, MKS Base v1.4, 2 channel Sainsmart Relay Module and the LCD into one unit. I really want to relocate the electronics before putting an enclosure around the printer.
