Replicator 2, CTC, extruder upgrade compatiable with 12mm V-groove Filament Bearing (VERSION_2) by BuilderOfThings

Last crawled date: 3 years ago

-This extruder upgrade works with V Groove Filament Guiding Bearing (3x12x4mm) as well as a normal flat Bearing (3x10x4mm)
-If (VERSION_1) works for you, there is no reason to make this one!!!
Here is the list of changes:
1)The pivoting arm was made even thinner at the top to make sure it will be compatible with all printer version (especially the ones with a cover on top of the extruder motors, like CTC printers, etc).
2) The v-groove gear now is easier to fit inside of the arm (less post-print work needed), also the V-groove hole was cut at the front to allow the smaller (3x10x4mm bearing) to be used in printers that don't use the V-groove bearing.
3) The base has a guide hole at the bottom for the filament. In previous design there was no guide, in some instances the filament wouldn't get loaded correct because of this.
4) Fixed offset spring alignment issue.
THIS IS MY FINAL VERSION... I don't see how it can be improved any further.
STILL doesn't fit your printer for some reason?!! SERIOUSLY?? The 3dm file is provided!! As always! Make your own changes :) Peace and love.
