Ender 3 & CR10 Direct Drive Assembly for BMG Extruder with Hero Me Remix

thingiverse

Jan 2020: I'm excited to share my latest design - Hydra Fan Duct & Tool Change System, which I believe outshines the Hero Me remix in many ways. Check it out here: https://www.thingiverse.com/thing:4062242 Update: Nov 23, 2019 I've just uploaded Direct Drive Bracket V2, featuring a revised mounting frame that allows for easier stepper motor assembly at an angle to feed the drive gear into the BMG housing. This design is a variation of my DIY Direct Drive Assembly, tailored to fit a BMG Extruder or similar clones. I've tested it on a CR10S and it works flawlessly. Although it's still marked as WIP (Work in Progress), I'm leaving it up for now since I might revisit it later. The basic assembly is similar to my previous DIY Direct Drive and Hero Me Remix designs, but this one has some unique features. You can find images of the fixing bolt positions and sizes during the assembly process. Please note that due to varying tolerances in BMG Clone Extruders, this design may be challenging to assemble on certain models. Specifically, the collar around the Direct Drive Bracket makes it difficult to insert the motor gear at a 30-degree angle. If you're forced to push the motor assembly into the extruder, it might be tough to put together. I've encountered similar issues with three different BMG clones I have, each with unique tolerances. One of them slides together seamlessly, but the others require more effort. This design only includes the Direct Drive Bracket and the duct base. You'll need to use a preferred set of ducts from one of my related designs - links are provided below: https://www.thingiverse.com/thing:3774121 https://www.thingiverse.com/thing:3881061/files I printed these parts with Prima Select Light Blue PETG, using 3 perimeters and 40% infill on an Ender 3 Pro & Ender 5. Neither part requires support. If you need further details or clarification, feel free to comment below!
