A fully-printed mount for the Titan Aero extruder. It uses printed bearing bushes, along the lines of this one. If you're printing these for the first time err on the side of making them a bit loose rather than too tight. They will loosen up a little after several hours of printing.
The main carriage is printed in one piece, and seems to work well. It has a few mounting points for cables, etc. I planned to attach the part fooling fan opposite the extruder, but with a large blower, there wasn't enough space. I reverted to the stock blower since the big one didn't generate much pressure.
The fan duct here is a placeholder. Ping me if you need a working one, I think I have a usable design now.
I'm using the stock ANET board. This means you need to keep the old stepper since the anet board doesn't seme to have the current to drive a low-profile stepper.
You need to reverse both the extruder drive, and the X-axis drive. You also need to be able to adjust Z about 20mm lower than with the stock setup. This may help.
Bear in mind that you will loose 15mm of Y travel using this setup, but it's a big improvement. I'm able to print 200x200 at least with the oversized bushing shown.
