In the Cx sections (specific/custom chassis), you’ll notice that most chassis are branded either Master, Knight, or Padawan chassis (while some other very specific chassis can get different names as don’t belong to any range, or the above mentioned chassis can also have more variations, like Knight Outcast, Rogue Master, ….).
Here is what it means:
Padawan: An entry level line of chassis, for budget builds and with a straightforward install approach (easy to build). These chassis have a basic and functional design, and are printed in plastic only. The perfect choice for beginners.
Knight: The mid-range chassis level. It is most often an assembly of various 3D printed plastic parts, with a detailed design and crystal chamber to make saber look great. They also come with instructions to walk you through the install procedure. The best choice for a great saber (and reveal) design, while still keeping the cost moderate.
Master: The top range chassis for DIYers. These chassis are an evolution of the knight including a crystal chamber detailed assembly of parts, that can be printed in metal (steel, bronze, brass). It will give your saber an amazing look and reveal, with Crystal Chamber parts that would not be achievable through classic machining processes. They are also relatively easy to assemble and instal by following the instructions posted on the website (link in the Shapeways items description). It is still possible to print the crystal chamber parts in plastic and paint them to keep the cost down. The best choice for a top off the line saber!
Grand Master: An exclusive and limited range of chassis. Not available to purchase, they can only be found in completed sabers made by GOTH-3Designs and partners like NerfworXlab. They are mostly full metal chassis with crystal chamber, featuring an awesome design to turn a lightsaber into a true masterpiece. These sabers will be only available through GOTH-3Designs eBay shop or partners.
