TTT - Titan Take Three
E3D Titan mount for the ANET A8 and other Prusa i3 clones using bearing blocks on the X-Axis. OpenSCAD code included so that you can modify as needed. Two parts, base plate and mount, are required and five; fan mount, captured fan nozzle, sensor mount, and cable chain ends are optional. The parts are designed separately to allow printing with mimimal supports.
1) The base plate or carrier, which can be printed with or without the integrated belt attachments. The belt attachment can also be printed separately using the SCAD file to generate the STL by changing variables. Nut catches are provided for the front mount fan and sensor mounts and for the rear mount sensor mount. Thickness of the plate and mount have been kept to a minimum to allow re-use of the original screws to attach to the bearing blocks.
2) The extruder mount, which includes a tab for either cable restraint or mounting a cable chain. The extruder mount design allows full access to the Titan's features. I use a shorter motor (34mm vs 40mm which fine with the gearing advantage of the Titan, and also serves to lighten the assembly. The original motor can be used with this assembly. The mount uses the same holes as the bearings, so leave out the top screws on all three bearings when mounting the base plate to the bearings. You will add them when you install the mount bracket.
3a) OPTIONAL: Side fan mount which allows the stock ANET fan to be rotated so that the air intake faces the extruder. Includes a hook at the top to keep the wires away from the X-axis switch. This assembly could be replaced with thing:1354526 by 3DIYOriginal which would also replace the stock E3D fan. There are also several other options available.
3b) OPTIONAL: Captured fan nozzle replaces the original nozzle with one that will not droop or come off.
4a) OPTIONAL: The rear sensor mount, which mounts from the back and uses holes for the belt attachment. This works with either my plate or the original ANET hot-end/extruder. Optionally, use the ANET sensor and plate if you have them. This is set for 12mm diameter sensors, but the SCAD file will allow easy modification.
4b) OPTIONAL: Front sensor mount places the sensor in front of the motor. While closer to the nozzle, I did not like this position personally as it is off the build plate when the nozzle is homed.
5a&b) OPTIONAL: Cable Chain mounts. One screws to the top of the extruder mount and the other simply clamps on top of the x-motor mount. Standard chain should work well.
STL files have been included for each option, based on a 34mm motor length. You can use the OpenScad files to create your own STL files. The fan mount, plate, rear sensor mount, and extruder mount are in a separate files. The 'rounded_cube.scad' is a routine that I use anytime I need a cube with rounded edges and is used as an include by the other programs, so simply place it in the same directory.

9/27/16 fixed issue with side fan catching on X-limit switch and added optional cable chain attachments. Modified Rear Sensor so that it prints flat and lightened it.
9/28/16 re-enforce joints on mount.
9/30/16 Uploaded tweaked side fan mount and captured fan nozzle. Uploaded pictures.
10/5/16 modified rear sensor mount to include nut capture for top nut.
