need extra push but you like new i3 x carriage and new i3 extruder style?
collaborative wade's takes too much space and causes your motor to overheat and skip steps? collaborative wade's idler and latch drives you nuts?

struggle no more. here i've snapped two plain i3 extruders with solid blocks in blender.
feel free to use. blender file included - note motor block is not visible and transformations are applied.

i've printed it - it's so big it broke my glass during cooling - be careful.

it's NOT tested yet - but as almost no changes done it should quite certainly work. it'll be certainly heavy so try to adjust your jerk and acceleration settings to avoid disappointments. probably more sane to use in bowden configuration.
