If you make this, please post the make! I want to see everyone's printers! This is the stepper I used: https://www.amazon.com/gp/product/B07FRDM8X8/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 Its less than $10 with Prime shipping and works fantastically. Edit 8/21/2019: After installing, I measured new probe offset is X -28mm, Y -2mm. Z-offset for BLTouch is 1.600mm, but this should just be a starting point for you. I used no washers between the mount and the probe. I printed v1.2 last night and installed it this morning. v1.3 was uploaded and the only tweak was removing a little material to the cable management on the left side so the stepper motor fit a little better. Overall, I think this is 'done'. It prints well in the orientation shown, it mounts solidly and works great. Edit 8/20/2019: v1.0 was installed on the printer and I found a very easily usable part cooling fan here: https://www.thingiverse.com/thing:2085425 Fits on perfectly and works very well. My Z-offset is -1.95mm, and the probe offset is X -49mm, Y 0mm. I've also updated to v1.2 to include some cable management reliefs with slots for cable ties. I wasn't a fan (no pun intended) of the 40mm fan duct on the original. I removed it, added a BLTouch mount and tweaked a few things here and there to try and lower mass. This is still very much a work in progress. The BLTouch holes need to be modified and I have no idea yet if its even at the correct height. Edit: v1.1 uploaded. I moved the BLTouch mount much closer to the hot end nozzle and shaved off 5mm of width of the overall part. After putting a 23mm NEMA17 stepper on, the entire part stuck out about 5mm past the end, so it was unneeded. Pics uploaded are the original v1.0. I'll be printing out a v1.1 shortly and will upload photos of that in a day or so. I used this in conjunction with my E3D V6 Bowden -> Direct drive adapter here: https://www.thingiverse.com/thing:3752759
