Why this one

Converting rotary motion into straight-line reciprocation in a printable demo mechanism.

The crank disc turns on the frame axle. Its pin rides in the yoke's vertical slot and drives the yoke along X between the two rails. The rod is seated in the yoke's right face and slides through the frame's bearing block. The stroke is 2 times the crank radius.
