All of the parts needed to upgrade a Robo3D R1+ to an E3D Titan Extruder. Using these parts the extruder will be able to handle any material you throw at it: from PLA, ABS, PETG, Vinyl, even TPU at speeds greater than 60mm/s (yes, including TPU with retractions enabled). The fan duct can easily be removed when printing parts that don't require cooling.
Use the recesses inside of the gantry to secure the cabling with zip ties. TPU performance is very specifically tied to the cap-tubes modification shown in the images. Using great care, it should be possible to drill out the filament guide and cut the PTFE such that the tubing goes right up to the gearing on both sides. It is important that the PTFE angle/position match the gearing as much as possible to ensure smooth flexible printing performance.
For the LCD holder, I recommend the following model: https://www.thingiverse.com/thing:87250
The filament tower was designed to be used with the Flexible, Adjustable spool holder: https://www.thingiverse.com/thing:3331712
Purchase all new rails from McMaster-Carr. They're worth every penny. I'd recommend upgrading the linear bearings as well, but that isn't nearly as important as the rails.
Required pieces:
8mm rails (15x) #4 screws, 0.5" (1x) #4 screw, 0.75" (2x) M5 bolts, 10mm (4x) M5 bolts w nuts, 14mm (2x) M3 bolts w nuts, 12mm
Screw placement:
(8x - #4 - 0.5") - Gantry cover (4x - #4 - 0.5") - Cold Break Fan (2x - #4 - 0.5", 2x M3 bolts w nuts) - Adjustable belt tensioner (1x - #4 - 0.5") - X-axis bump stop (1x - #4 - 0.75") - Fan duct (2x - M5 bolts) - 50mm blower fan (4x - M5 bolts w nuts) - Filament tower
