Ender Modular Hotend Carriage

Update 2020-03-25:

• Now completely compatible with the Ender 2, 3, & 5!
• ReplacedBLtouchMount &HotendMount-V3_1 with updated versions. I removed the heatshield & made a few minor usability improvements.
• Added:Merged_Hotend&FanMount-V3_2.stl for people who want to print this with materials other than ABS/ASA. It requires supports to print but should be completely doable.

Update 2019-10-08:

Replaced all files with slightly updated versions.

Changes:

• Fixed minor tolerance issues (the issues probably wouldn't bother anyone but me)
• Parts are now easier to print
• More clear part naming
• The .stp file now contains all parts
• The hotend mount now allows for more airflow
• Please do note the image of the sliced parts. That screenshot shows where the supports are needed as well as optimal print orientation

With that, I think this project is finished. I can't think of any other changes to make.

I should also probably add that this probably fits the Ender 2,3, CR10 & other variants. Unfortunately, I don't own those devices to test.

Okay, where to start..

Interesting things about this hotend mount:

• It's completely modular
• The part cooling mounts allow you to strap on any cooler you like (you may need to bodge on a mounting surface or something in meshmixer depending on your part coolers of choice)
• The BLtouch part of this can also be easily swapped out, excluded, or replaced with whatever
• The BLtouch offset is 30.4,0,3 (x,y,z)
• The hotend mount redirects coldend cooling air upwards through internal vents/channels so it doesn't interfere with your prints
• It's very compact (great if you're using an enclosure)
• It has a heatshield to protect your BLtouch (or other z-probe) from getting too toasty

Required hardware:

• Microswiss or stock creality hotend (maybe others fit???)
• Two 5015 Blowers (or whatever you need for coolers you decide to strap to the sides)
• A 4020 axial cold-end cooling fan
• Zipties (you can use screws instead to mount the 4020 fan if you'd like)
• For optional remote part cooling blowers: A good amount of 1/2in OD, 3/8in ID tubing

Assembly notes:

• The FanMount & HotendMount need to either be glued or ABS welded together. Let me know if you want me to upload a fused STL. It just seemed like a pain to print like that.
