CR10 CR-10 direct drive adapter to connect to Titan

thingiverse

UNTESTED SEE BELOW. This goes into the M10 0.9mm threaded fitting place on the CR-10 hot end heat sink, and allows the use of some direct drive feeders. There are two variations, each with & without support. You need to cut the teflon tube at the heatsink entry, maybe just fractionally higher (0.5mm?) so that it is a tight fit, but you do this and modify your tube entirely at your own risk. The two variations are 2.1mm orifice and 2.4mm orifice for the filament. Most people should use the 2.4mm orifice. Use the 2.1mm with "horizontal expansion" tuned to get an exact opening, or import it into a modeling program to change the hole as you wish. The supports work well, and break off easily. I haven't tested this in operation. I've fit-tested it, printed on an Ender 3 using a raft and the included support, and 0.12mm layer height. Also, I have placed it into a Titan housing, but I haven't tested operation with the Titan. I figure it will work fine for stiff filaments, but there could be a need for tuning of the hole size(s) for use with flexible filament. I would expect it to work, but you'll need to inspect your print and consider any mods to make it work better since I left some expanded regions to help you get regular filament through. And I would expect some trouble with flexibles if you print it at low resolution and there are abundant layer lines. This was motivated by a Facebook post by walstad83 and a Creality video for the Titan upgrade, here: https://www.youtube.com/watch?v=B9llAMvKcWM
