I tweaked the scad parameters and exported each gear individually in order to improve the printing parameters per gear.
Specifically I have changed the distance between axles to 41mm.
Beware that these gears are 11/45 and the standard gears that came with my Prusa i3 Rework is 10/43. So you will need to adjust your extruder steps per unit by calculating the ratio difference: 10x45 / (11x43) = 450 / 473
Make sure you line up the gears well before tightening. I did this by first fastening the large gear and leaving the small gear loose on the motor axle. Then I spun the large gear around and tightened the small gear between the two extremes I found. This way the front of both gears are about flush with each other.
