Bowden stepper mounting bracket

thingiverse

I designed a custom screw-down bowden stepper bracket, tailored specifically to fit one of mine snugly. This same type unit comes with a Tronxy P802E. All screws are countersunk, providing a secure fit that renders the 2 x M3 mounting screws optional. I operate my printer without these screws and still manage to remove the servo from its mount when dealing with filament issues - the holes are there if you prefer extra security. The intended use is to mount it on top of a Lack cabinet for easy filament loading, but with some modification, it can be used in various applications other than direct overhead mounting. When changing filament, heat up the nozzle, press the extruder drive release, and then feed a small amount manually before withdrawing it from the print head. The filament forms a glob that won't easily return to the heat break, allowing for easy removal after flushing.
