Replicator 2 extruder replacement with no overheating issues v2 by itzalak2 Apr 5, 2013

Description

Trying to improve the extruder mod v1 loaded last month 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.

I used 3 or 4 designs based on whpthomas and other made by me but I had problems due to deformations of the top part that goes from the spring to the turning point caused by prolongated hot and pressure made agains the extruder.

This design works very well for me and as there is not any long PLA part that suffers the pressure of the spring there is no deformation. The max pressure point is into the groove where the spring lies but as it is into big-solid PLA part the deformation is very difficult.
This is interesting; how well does it work? Have you tried any of the other minimalist extruder mods out there?

Instructions

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.
