Geeetech A10 Extrusion motor bracket

Having a bowden type of extruder, I had problems with flexible filament. So I designed (with caliper) a new version of the piece in the middle between the entry and exit of the filament in the extruder motor, with the goal of a tighter coupling of the filament exit to the pushing gear. Along with the replacement of the nozzle with a steel one, this made TPU printing feasible and reliable.
