Prusa i3 X Carriage Adapter for Bulldog XL Extruder

thingiverse

An E Carriage adapter specifically designed for the Bulldog XL and Prusa i3, sporting the distinctive Aurora design. The device is carefully engineered to accommodate the E3D fan shroud in its upright position. By mirroring the Bulldog XL based on a detailed YouTube tutorial, I was able to create this essential upgrade. With a high-precision TGY-1440A sub-micro servo in play, which can be found at hobbyking.com, the Z probe module ensures seamless functionality. If using a servo isn't feasible for you, there's an alternative setup featuring a rubber band snap mechanism – a clever idea conceived by fellow Aistaca, accessible at thingiverse.com. This innovative adapter is fitted with a reliable DM3 micro switch from Jaycar Electronics, providing foolproof control over operations. Calculations were performed to perfectly align the Bulldog XL with the mounting groove, preventing any structural irregularities. In terms of fastening hardware, the bulk of it features M3 x 15mm screws, catering for robust support. The added benefits include active cooling and enhanced performance by upping print speed significantly – by an impressive 1,200%! Notably, all design aspects account for precise tolerances. Visit thingiverse.com to access further images illustrating this innovative technology. You'll need the following components to complete assembly: M3x15 screws, Cable ties (for Z probe installations). As advised in printing settings: ABS as preferred print material. Due to the narrow structure of some sections on the Z arm, experts recommend incorporating components of equivalent height to assist during printouts. As an additional option, use a part with built-in layer assistance, guiding your printer away briefly for improved outcomes. Alternatively, simply using snap-based probe module shouldn't yield difficulties (except for perhaps ultra-high speeds).
