BMG V6 ABL MGN12H Direct Drive System for Ender 3 and Clones

prusaprinters

<p><strong>Minimal print area loose. No end stop adjusting...</strong></p><p>This project is based on SK-Tank CF BMG Dual 5015s Mount by declinox. <a href="https://www.thingiverse.com/thing:5182358">https://thingiverse.com/thing:5182358</a> ) I find his design while looking a project for “MGN12H rail system, BMG extruder and E3D V6 hotend combo” for Creality Ender 3 V2. I love this design so much and start to modify it for Ender 3 and clones.</p><p>When I founded some mistakes in my design, I redesigned some parts. I benefited from the awesome EVA 2 project in newly designed parts. EVA 2 project is made by Paweł Kucmus for more info; please visit; <a href="https://2.eva-3d.page/step_files/">https://2.eva-3d.page/step_files/</a></p><p>Also i added some parts from Hero Me Gen VI from Mediaman. <a href="https://www.printables.com/model/39322-hero-me-gen7-master-suite">https://www.printables.com/model/39322-hero-me-gen7-master-suite</a>.</p><p>UPDATES<br>30.11.22 All new files uploaded. Now my duct system works fine! Very happy...<br>23.11.22 New experimental parts uploaded. New gantry/main body, matched belt mount, BL Touch Mount and Cable mount... Those parts are in experimental status<br>13.11.22 All new files uploaded</p><p>PLANNED<br>-Mount for Titan Extruder coming soon</p><p><strong>WARNINGS</strong></p><p>Please consider that; some parts may need to be filed and sanded. I suggest to print parts with ABS or PETG. I re-design all parts for easy printing with minimal support and easy maintenance.</p><p>Since I don't know much about 3D designing softwares, i made all my drawings on Tinkercad. You can find a lot of cosmetic defects, but all parts can work functionally.</p><p>&nbsp;</p><figure class="image"><img src="https://media.printables.com/media/prints/317795/rich_content/450055a3-4103-41c3-8bb5-0132f8147cc1/kybele-1.jpg#%7B%22uuid%22%3A%22e77361d5-17e8-4155-a56a-4be373e59f5c%22%2C%22w%22%3A1031%2C%22h%22%3A938%7D"></figure><p><strong>PART LIST</strong></p><p>Main-Body-Back - Heart of toolhead system; x gantry adapter. Its a combination of EVA by Paweł Kucmus, Hero Me Gen VI by Mediaman and SK-Tank Mount by Declinox. I added matched MGN12H holes, added extra ventilation holes for better hotend cooling.</p><p>Main-Body-Front Taken form EVA by Paweł Kucmus. I added some holes for easy assembly. This part also clamp E3D V6 hotend to the main body.</p><p>Belt-Mount - Taken from Hero Me Gen VI by Mediaman. Modified for better rigidity</p><p>BMG-Extruder-Mount Taken form EVA by Paweł Kucmus. I added some holes for easy assembly and re-mixed for better placement for Ender like printers..</p><p>Fan-Mount-Left / Fan-Mount-Right Original files from declinox. I re-designed fan mounts. I thickened the edges. For better 5015 fan stability i added a frame. This frame is taken from Hero Me Gen VI by Mediaman. Looks fantastic :)</p><p>Duct-Left - Duct-Right Original files from declinox. Re-designed snap on fan ducts for better consistency to the new design. You can find different ducts for E3D Evo or Volcano as remix on Thingiverse...</p><p>BL-Touch-Mount - This design is taken from "Adjustable BL-Touch sensor mount" by MyStoopidStuff. I re-designed for optimal placement and rigidity <a href="https://www.thingiverse.com/thing:3148733">https://www.thingiverse.com/thing:3148733</a></p><p>Cable-Mount Taken form EVA by Paweł Kucmus. I added some holes for zip-ties and re-design for better fitting</p><p>Cover-With-Logo Taken form EVA by Paweł Kucmus. I hardly modified these files to match my design.</p><p><strong>INSTALLATION</strong></p><figure class="image"><img src="https://media.printables.com/media/prints/317795/rich_content/cc228c4e-7d70-4344-8dbb-727cbf579cd8/kybele-2.jpg#%7B%22uuid%22%3A%22172dc0e9-7f68-4555-941f-ab61feaf80a9%22%2C%22w%22%3A1445%2C%22h%22%3A1084%7D"></figure><p>Place 5 x M3 nut to BMG-Extruder-Mount.

You will need 6 x M3 heat-set inserts for the front of the duct system.</p><p>Now the backside.. Place 4 x M3 nuts in total to the back side of the plate. Then place 2 x M3 heat-set inserts to the adapter. You can install heat-set inserts by pushing them into the plastic with a soldering iron. I use screws from local market. Dimensions are: M3 5,5 x 4,3mm Place 2 more M3 nut as shown in the picture..</p><p>You will need 5 x M3 nut and 8 x M3 insert in total</p><figure class="image"><img src="https://media.printables.com/media/prints/317795/rich_content/01b9e510-b3b9-473a-a698-56a0404e2e11/kurulum-2.jpg#%7B%22uuid%22%3A%22752020aa-11d6-4136-99ab-dbfbd23051bd%22%2C%22w%22%3A1445%2C%22h%22%3A1084%7D"></figure><p>Now lets join Main-Body-Back and BMG-Extruder-Mount.
