Replicator 2 extruder replacement with no overheating issues v2

Trying to improve the extruder mod v1 loaded last month http://www.thingiverse.com/thing:60574 I decided to make a new and cheap design using a 9 mm diameter bearing and one clothespin that everybody has at home. The spring of the clothespin has the same internal diameter than the extruder default bolts si it is "perfect.
Print all the pieces and keep in mind that the small piece that goes into the gear is a small piece and some printers will print it bigsmaller that design so maybe you have to adjust the tube diameter.
Cut one bended part of the clothespin to fit it in the extruder back piece and bend the other leg a little nearer to spring to adjust the turn radio (in my case 2-3 millimeters are enough).
Put the smallest piece into the bended leg of spring and insert the bearing then put the st into the extruder rear part.
To mount the front part you only have to rotate 90 degree, push against the rear part of the extruder and rotate he front until all pieces are aligned. Then mount into the motor.
