Ender 3 Direct Drive BMG - Single Blower

thingiverse

I like a mix of different projects, and I've always wanted a direct drive so I did some adaptation in Fusion 360. The main benefit of the design is that it's very easy to access everything. The design here (https://www.thingiverse.com/thing:2784599) was great but didn't have BL Touch support. It also relied on another cooler here (https://www.thingiverse.com/thing:2612897), so I decided to combine them into one part. Finally, I added the adjustable BL Touch mount by mediaman located here (https://www.thingiverse.com/thing:3182917). Additionally, I updated the bowden retention clip to have a handle for easier installation and removal with needle nose pliers. There are 2 BMG/Stepper brackets. I've only tested the one in the picture. I tried to label them clearly. If you're mounting it like the picture, just check if your wheel is facing towards or away from you and print the appropriate bracket. If your wheel faces away and it doesn't fit, let me know or feel free to edit the F360 file I've included. For the main cooler part, print flat with supports. The other parts don't need support. At some point, I will design a cable holder that can screw into the 2 holes I added to the back of the direct drive adapter, but I'm not sure when it will be ready. #define X_PROBE_OFFSET_FROM_EXTRUDER -42 // X offset: -left +right [of the nozzle] #define Y_PROBE_OFFSET_FROM_EXTRUDER -16 // Y offset: -front +behind [the nozzle] Feel free to see my non direct drive version here: https://www.thingiverse.com/thing:3910281
