On the Replicator 2 and Replicator 2X as well as many other printers, there are connectors on the extruder fan wire to make swapping parts easy. The only issue is these connectors are difficult to apply the proper directional pressure to. The means we have seen many connectors damaged because they were taken apart with the wrong tool or left attached when they maybe should have been disconnected.
To solve this we have developed a small and easy to 3D print wedge tool that will allow safe and easy separation of this connector. The STL files are available on Thingiverse.
To use the tool you overlap the two parts between each side of the connection and then squeeze them together. This will safely separate your connection and requires minimal force to do so.
The string is installed between the parts to help prevent losing these tools as they are very small.
