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

Minimal print area loose. No end stop adjusting... This project is based on SK-Tank CF BMG Dual 5015s Mount by declinox. https://thingiverse.com/thing:5182358 ) 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. 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; https://2.eva-3d.page/step_files/ Also i added some parts from Hero Me Gen VI from Mediaman. https://www.printables.com/model/39322-hero-me-gen7-master-suite . UPDATES 21.05.23 New Cover file added - Main-Body-Back V2 added. New mainbody has more heat inserts. You can choose which you like… 21.04.23 Cover Without Logo added.. 20.04.23 Matching ADXL345 Mount added. Needed screw sizes added (thanks to koalified) 19.04.23 Files re-organized add missing files (thanks to koalified) 18.12.22 Mount for Titan Extruder added 30.11.22 All new files uploaded. Now my duct system works fine! Very happy... 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 13.11.22 All new files uploaded PLANNED --Minor improvements WARNINGS 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. 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. 📷 Image redacted — claim this model to add your own media PART LIST Main-Body-Back or Main-Body-Back V2 Heart of toolhead system; x gantry adapter.
