BazBot v3 Upgrades - Titan Extruder Mod

thingiverse

I wasn't thrilled with the Bowden performance on a long tube. Issues arose when certain filaments roughed up the interior of the Teflon tube, increasing friction significantly. Concerns also lingered about the problems that would arise if attempting to print flexible materials. Since I was planning to upgrade to a geared extruder anyway, I designed it to be directly mountable to the effector and function as a direct drive system. I'm extremely satisfied with the results. There are three more holes in the effector designed to house 5mm LEDs, but they're not mounted in the picture. For the LCD Mount, only one bracket is provided. Simply mirror this part in your slicer for the other side. The design is intended to fit a ReprapDiscount LCD. Post-printing assembly involves using M3 screws to attach the LCD housing to the LCD and brackets to the LCD enclosure. M5 screws secure the brackets to the aluminum extrusions. M3 screws are used to attach the Titan extruder/Nema 17 mounting bracket to the effector, but they do not thread into the effector itself. T-nuts (or any other type of nut) are used underneath to secure the mount. This design was created by remixing from an existing addon for my BazBot v2. A control knob was sourced from a JolietDelta design, which fits snugly in place. The majority of the BazBot components were designed using SolidWorks. To challenge myself and learn AutoDesk Fusion 360, I designed all the items included here.
