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

thingiverse

This upgraded extruder works with V Groove Filament Guiding Bearing (3x12x4mm) or a normal flat Bearing (3x10x4mm). If Version_1 already meets your needs, there's no point in trying this one. The list of changes includes: 1. The pivoting arm has been made even thinner at the top to ensure compatibility with all printer versions, including those covered by printers like CTC models. 2. The v-groove gear is now easier to install within the arm, and less post-print effort is needed. 3. The base of this design features a guide hole at the bottom for the filament. 4. The issue with offset spring alignment has been fixed. This version can't be improved upon further; it's complete and fully refined. Your printer still doesn't work with this upgrade? Seriously, there's an option to create your own modifications. The 3D model is available as always.
