TTT - Titan Take Three E3D Titan Mount for ANET A8 and Other Prusa i3 Clones Using Bearing Blocks on the X-Axis I designed this E3D Titan mount for use with the ANET A8 and other Prusa i3 clones, utilizing bearing blocks on the X-axis. OpenSCAD code is included so you can modify it as needed. Two parts are required: a base plate and a mount, while five optional components are also available: fan mounts, captured fan nozzles, sensor mounts, and cable chain ends. 1) The Base Plate or Carrier The base plate can be printed with or without integrated belt attachments. If you want to print the belt attachment separately, you can use the SCAD file to generate an STL by changing variables. Nut catches are provided for the front mount fan and sensor mounts as well as the rear mount sensor mount. To allow re-use of original screws to attach to bearing blocks, I kept the thickness of the plate and mount to a minimum. The extruder mount is designed with full access to the Titan's features in mind. 2) The Extruder Mount The extruder mount includes a tab for cable restraint or mounting a cable chain. It allows you to use a shorter motor (34mm vs 40mm), which works well due to the gearing advantage of the Titan. You can also use the original motor with this assembly. I designed it so that you can install the base plate on the bearings without using top screws. 3a) OPTIONAL: Side Fan Mount This option allows you to rotate the stock ANET fan so its air intake faces the extruder. It includes a hook at the top to keep wires away from the X-axis switch. You could replace this assembly with thing:1354526 by 3DIYOriginal, which would also replace the stock E3D fan. 3b) OPTIONAL: Captured Fan Nozzle This optional component replaces the original nozzle with one that won't droop or come off. 4a) OPTIONAL: Rear Sensor Mount The rear sensor mount is designed to work from the back and uses holes for belt attachment. This works with either my plate or the original ANET hot-end/extruder. Optionally, you can use the ANET sensor and plate if you have them. This mount is set for 12mm diameter sensors, but the SCAD file will allow easy modification. 4b) OPTIONAL: Front Sensor Mount The front sensor mount places the sensor in front of the motor, but I didn't like this position personally as it's off the build plate when the nozzle is homed. 5a&b) OPTIONAL: Cable Chain Mounts One cable chain mount 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 are 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 separate files. I've also included 'rounded_cube.scad', a routine I use anytime I need a cube with rounded edges, which is used as an include by the other programs, so simply place it in the same directory. Thom Sturgill 9/27/16: Fixed issue with side fan catching on X-limit switch and added optional cable chain attachments. 9/28/16: Re-enforced 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. Print Settings Printer Brand: RepRap Printer: Anet A8 Prusa Rafts: No Supports: No Resolution: 0.20 Infill: 24% Notes: 24% infill in Cura produces a crosshatch in each layer which works well. Above that, a lot of retractions occur and I don't believe it's as strong. Post-Printing There are numerous nut catches for 3mm nuts. Not all are needed. Nuts should fit in easily if your extrusion level is correct, but a soldering iron works well if they don't. 6 on base plate - 2 for rear sensor mount and two each side for accessory mounts. I used one on the right for strain relief for E3D wires, 2 on left for fan mount. 4 on side fan, only two are used depending on fan model. 2 on cable chain attachment to attach it to extruder mount.
