Hybrid direct flex optimized extruder with 8x12x3.5 bearing

This is the extruder I designed specificaly as a replacement of wade geared extruder of prusa i3 (mk1/mk2).

This one is easily printable (there are only 2 parts requiring printing in ABS). The rest can be printed with PLA/PETG.

It uses one of the these 8x12x3.5 bearings instead of the big ones.

Because of how the motor is placed, there is minimal force (twisting momentum) on steel rods.
Model is split into parts that can be printed without supports.
