Aluminum Arms For the Replicator 2 & 2X
by bottleworks, published
Have you been having issues with your MakerBot Replicator 2 or 2X Z Stage arms warp or excessively vibrate? The Replicator series is a Revolutionary set of 3D printers pushing the limits of small scale 3D printing. As people reach new advances in desktop 3D printing, stability and consistency are critical. The OEM Z Stage arms are made of ABS plastic. Unfortunately, when the plastic arms are exposed to the heat generated by the HBP (Replicator 1 & 2X), they warp, sag, and otherwise move. This warping and sagging make it Incredibly difficult to have a consistently level HBP. As a result, constant tweaks and adjustments are required. Another issue is the low mass and flexibility of the plastic arms. During high speed printing, the OEM arms, lightly vibrate. These vibrations contribute to further distort the object being printed. This is less apparent in the Replicator 2, but artifacts continue to appear during high speed printing.
Virtually eliminate these issues by upgrading to custom CNC milled aluminum Z Stage arms. These replacement arms are made out of a single solid piece of 6061 aluminum.
- The arms are designed to replace the original plastic arms.
- There are 4 bearing retainers which you can print yourself, or can be purchased with included hardware.
- 4 new LM10UU linear bearings for the Z axis included
- No more constant adjustments due to unwanted arm movement.
- Greatly reduced platform vibration (springboard effect).
- Each set comes with step-by-step installation instructions in full color.

Corrected bolt spacing. At some point, I noticed that it didn't quite match up with the OEM arms. It was never caught because the backplate must be replaced. So, I updated the arms.... Consequently, I had actually forgot that I did that, until somebody tried to install set of arms with the updated drill pattern. If anyone was accidentally sent the incorrect version, please email me.

Print the bearing plates with 100% fill.
Print the rest with 10-12% infill, 2 extra shells.
The "full" back plate is an optional version that helps remove some "hidden" areas where plastic bits can fall into and get lost.
