CR-10 Direct Drive extruder with integrated RSE-2

thingiverse

Got another one. This time I combined the beefed up direct mount with RSE-2 extruder as a single unit. Lined everything up with Ross_K's carriage model and my own representation of the MicroSwiss heatsink. The Noclearance file lets you add your own cutouts to clear any cooling solution you have in place. The fang file already has pre-clearanced cuts for 2bedom's MicroSwiss fang. Edit: I added a FilamentSaver file to test attachment to the carriage, position of the outlet tube to match the heatsink Bowden, and sizing of the hole to receive the Bowden. I'm planning on printing out a low infil PLA test part this morning to see if there are any problems before switching to PETG. Update 2/26: Printed out the FilamentSaver in Hatchbox white PETG. It fits perfectly except for the hole for the bowden tube, which is too small. I'm measuring about 3.5mm when it was supposed to be 4.2mm. I don't know why it shrunk so much more than everything else. I uploaded three MKII files with the bowden hole enlarged to 5.2mm from 4.2mm, a 120% increase to match the shrinkage encountered. I know it will probably cause problems since the full versions are printed at a different orientation than what I printed the test. Update 2/28: I added an MKIII Fangclear file and fixed a small clearance issue with the left guide wheel. I also enlarged the hole for the bolt that holds this wheel on, which was a little tight on my FilamentSaver model that I printed. I added a cover for the RSE2 extruder with a drag chain attachment molded in. Hopefully it will line up well enough and not get in the way. I used stevenfayer's Z chain links; I don't have a fixed end modeled yet. The hole in the direct drive mount is for a 20x20 heatsink on the stepper, by the way - I forgot to mention that. I added an MKIII-BowdenIn file. You should be able to thread a 5mm pushlok into it; made hole 4.78mm. Update 2/28: I printed out the MKIII Bowden version. I was right, enlarged the hole too much - 5.2mm in CAD came out 4.8mm on print. Still going to install it and make sure there are no other problems. It looks good just looking at it, but got some stringing and ugly places. Used Hatchbox white PETG.
