Bottleworks created some amazing aluminum arms for both the Replicator 1, 2 and 2x. He sells them online, and they are the must-have modification for your Replicator. I have a set on my Replicator 1 Dual and LOVE them! When I got a FlashForge, I bought a set for a Replicator 1 Dual, and tried to install them on the FF, but of course, the FF is not an EXACT copy of the Rep 1 Dual. Some of the mounting holes for the build platform, are different, as well as the location of the Z axis drive hole. So, design a new part to replace the build platform holder, to allow me to install the awesome Bottleworks Aluminum HBP arms on my FF. Hopefully this part will help other make the same modification to their FF.

Take the Corel Draw file (CDR), or the DXF File, find a friend or colleague with a laser cutter, and cut out a new plate, and install it on your printer.
