Description

This is an upgrade kit for the Delrin Plunger. It can be used for many RepRap based 3D printers with dual extrusion setup including Makerbot Replicator 2X If you are experiencing print failures every time you use a new filament, that is because of the existing plunger on your extruder that cannot adapt to the diameter tolerance of the cheaper filaments. I have had issues even with some of the Makerbot filaments, but this upgrade will solve this issue.
