Here is Luke Skywalker's Lightsaber as seen in The Mandalorian TV series, Chapter 16.


This Grand Master Chassis is a completely brand new design.
And it's another masterpiece, not only packed with tech, but also lots of intricate details, and a removable crystal chamber to change the Kyber crystal! The chassis can be fully or partially revealed only by removing the grenade section of the hilt. There are 3 doors around the Crystal Chamber, making it a playful chassis. Note how these doors fit perfectly on the hilt middle section when opened? Eveything is designed at millimeter level :D

Introduction

  • Disclaimer

    GOTH-3Designs cannot be held responsible for any mistakes made by DIYers during their install. You must have a good understanding of what you’re doing, of the components used and the safety measures associated to them. Always wear protective gear when working on install (gloves, eye protection, …), GOTH-3Designs cannot be held responsible in case of accident.

  • Note #1

    Always use the smallest wires to make your install easier. There can be big differences between one wire type and another for the same AWG specs. PTFE Wires with the smallest OD are recommended such as those sold at The Saber Armory. A good wire management is also required, routing wires properly helps a lot saving space.

  • Note #2

    These instructions will not cover how to wire the soundboard, make sure to learn how to by reading the manual. We have also typical soundboards wiring available in the Padawan Tutorials. Always test your install along the way! Verifying that everything works after important steps is better than having to dismount everything because something wasn’t wired properly.

  • Note #3

    3D printed parts can have slight size variations which may require some small adjustments by the installer (such as sanding, hole deburring, … etc). Some metal parts could also be slightly bent, but are usually easily bent back in shape. This is all normal and part of the DIY build process.
