The ultimate Darth Vader Lightsabers replicas, KR-Sabers MPP kits will bring the Sith Lord Saber to life in the style of your choice thanks to WannaWanga accessories.


This Grand Master Chassis design symbolise years of MPP chassis design evolution, to reach an awesome chassis core to reveal. It's full of details and features, among which, the chassis can separate at the middle and the crystal can be removed (the Lightsaber changes behavior, sound and color according to the crystal inserted).

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.

Install Notes and Updates

  • These Build Timelaspe is showing the prototype build, some minor design changes have been done afterward and will be described here;

    Chapter 1 – Parts Preparation

    The following part has been updated, to add a door mech held with magnets:


    The part is now made of 2 parts held together, and the blue area needs to be cut away (Dremel):

    Then, 4 x 1mmx1mm magnets need to be glued in these holes:

    Chapter 4 – Chassis Rear Components Install (notes 1)

    The CC insert is held to the chamber shell using 2 x M1.6 screws and nuts.
    First, glue the nuts in their slots.

    Then, lock the CC instert with the screws (the CC insert will secure the locking ring part at the same time).

    Chapter 5 – Chassis Front Components Install

    Just for information, compared to the prototype, we have rotated the middle chassis connector clocking by 180° to make the wiring toward the soundboard easier.

Proffieboard Config

  • ProffieOS 8 Beta has been used on this saber, in order to allow the blade ID / Crystal swap feature.
