This is a slightly modified 1.75mm filliament variant of DiscoJohn's Taller Extruder Mount. This is designed to bolt to the upper mounting bolt of a Taz 3d printer, and requires a hexagon hotend. The Idler latch and Extruder Spacer are not my work, and are included here for conveniance only.
Why a taller extruder mount you ask? Why add the extra plastic weight? The reason is simple. by extending the extruder body up to the upper bolt hole, you allow the extruder to tie directly into the carriage mount structure, which eliminates front to back nozzle flex. Without this taller mount, a stock taz toolhead can flex +/- 0.15mm forward or backwards, particularily on corners when the extruded plastic drags on the part during a vector change. This eliminates that issue entirely.
It's an extruder body, so ABS or higher temperature material is reccommended. Pre generated built in support.
Print as normal, remove the built in support from the bearing pocket and the idler arm, install Extruder hardware as usual. You will need a longer bolt to replace the stock M3 extruder mount bolt (50mm long M3) . I also usually glue the extruder spacer to the extruder body for conveniance in mounting.
