Second Generation (MKII) – May 2014 – Improved materials specs (up to 120c), New design
This is a POLY URETHANE, MANUAL CAST kit to prevent melting/warping problem in long extrusions. It is an upgrade kit for the Delrin Plunger. It replaces the existing plunger in Makerbot Replicator 2X. It is not compatible with Replicator 1 Dual.
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.
You are buying a Makerbot Delrin Plunger replacement kit/Extruder Upgrade kit as shown in the first image. This is a picture of the actual item you will get(stepper motor/drive gear not included). This kit includes everything needed to replace the delrin plungers on your Makerbot Replicator 2X with a spring-loaded ball bearing assembly.
This product is assembled and is a revised version of what Makerbot introduce in several aspects:
Please note that this is a hand made part. The surface quality is not even close to a mass produced part however it does what it should do perfectly.
This kit includes:
1 X Base
2 X Swing Arm (mirror)
2 X 14mm flat-top hex screw – to mount the ball bearing inside the swing arm
2 X 22mm socket hex screw – for the pivot joint of the swing arm
2 X 10mm aluminum bushing – for the pivot joint of the swing arm
2 X 22mm flat-top hex screw – One to mount the back plate to your stepper motor (Top Right hole on the back plate)
2 X New Stainless Steel Ball Bearings
2 X New Compression Springs
Note: This is a DIY kit. It is not appropriate for mechanically disinclined. By purchasing, you acknowledge that you are aware of what you are doing.
- Material Polyurethane (heat resistant – up to 120C)
- One-piece arm with a stainless steel ball bearing shaft and ball bearing, so no worries about wear of the bearing holder after few hours.
- An aluminum bushing has been replaced with the 3d printed plastic pivot in the existing products for a maximum durability.
- Second Generation (MKII) – May 2014 – Improved materials specs (up to 120c), New design
