My Hero Print Head: Direct Drive for Ender 3 / CR-10
Description
Hi! I wanted to install a direct drive extrusion with a full metal hotend and a bmg by using the groove mount and I absolutely loved the Hero me gen 5. So I inspired myself of this excellent design to make this Direct Drive remix. Some direct drive mount are already existing, but it seems that all of them were using a printed part to mount the extruder and I didn't wanted to experience any vibrations in the extruder during retractions, so I bought this plate from aliexpress, and designed the "My Hero Print Head" out of this and the HMG5. This is my design of this plate: https://www.thingiverse.com/thing:4739740 and here is where I bought it: https://fr.aliexpress.com/item/32991887469.html?spm=a2g0s.9042311.0.0.ae636c37Huowqq I have an e3dv6, bmg extruder clone and pancake motor from Mellow: https://fr.aliexpress.com/item/4000072198732.html?spm=a2g0s.9042311.0.0.27426c37dHyJ86 and it works like a charm. I mounted this motor rotation indicator on it: https://www.thingiverse.com/thing:3956479 This is designed to mount a 4020 fan for the hotend and to use lightweight ducts from the Hero me gen 5: https://www.thingiverse.com/thing:4460970/files I installed the standard ducts for 5015 blower fans, but the forward ones should fit as well. I am currently using a TouchMi probe on this mount, so you will find the files uploaded. I used the same mount as the HMG5, but the height may not be the same for your particular probe and you may need to adjust your mount. You will need some M3 bolts out of the e3dv6, bmg extruder: - M3x10mm (*8) - M3x8mm (*2, can be replaced by 10mm ones - M3x20m (*4) - M3x50mm (*3) - M3 nuts (*12) Huge thanks to these designers who made my work a lot easier: - E3Dv6 hotend: https://grabcad.com/library/e3dv6-full-complete-hotend-assembly-1 - Bmg extruder: https://grabcad.com/library/bmg-extruder-1 - 5015 Radial cooling fan: https://grabcad.com/library/radial-cooling-5015-fan-50mm-dc12v-1 - 4020 Hotend cooling Fan: https://grabcad.com/library/fan-4020-1 - Ender 3 X Carriage plate with threads: (Can't find the link back) - Pancake motor: https://grabcad.com/library/17hm08-1204s-nema17-pancake-21mm-1 CAD files are available so you can measure/modify as you want. I would be very happy to see makes and remixes !! Have fun ;)
