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. 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

    The following instructions are created from the Prototype install. Some very small adjustments were done on the final chassis and the pictures might not reflect exactly the final product.

CHAPTER 1 – Pre-assembling the chassis


  • Step 1: Prepare the rods and tubes as per listed in the parts description.
    – 2 x 4mmOD tubes 37mm length
    – 2 x 4mmOD tubes 49mm length
    – 2 x 3mmOD tubes 19mm length
    – 2 x 4-40 Threaded rods 150mm length
    – 3 x 1.5mmOD rods 80mm length
    – 3 x 1.5mmOD rods 60mm length
    – 2 x 1.5mmOD rods 26mm length


    Polish and weather the metal parts if needed.


  • Step 2: Install the 2 short tubes into the main chassis, they serve to hide the wires.


  • Step 3: Install the magnets on the chassis and battery covers.
    The chassis takes 2 x 2mmODx2mm magnets and the convers 1 x 2mmODx1mm magents.


  • Step 4: Screw the 4-40 threaded rods on the blade holder.
    Add the 1st shell and CC insert (the insert goes first into the shell as shown on the picture, and then the shell is inserted on the rods.
    Verify that the battery doors close properly (or sand them to adjust if required).


  • Step 5: Install the magnets for the soundboard cover.
    They are all 2mmODx2mm, 2 on the main chassis, 4 on the cover and 2 on the Shell.


    Note: if using parts in Steel, due to the lower printing accuracy, the cover might not touch perfectly the chassis and shell. The magnets need to be the variable of adjustment, and will need to stand a bit out of the cover. Proceed step by step, first installing the magnets on the chassis side, then on the shell side.
    On the last step, place the cover with the shell magnet attached to it and a bit of E6000 glue on them, then insert the shell so that the magnet will enter to the desired depth).


  • Step 6: Insert the 1.5mmOD rods in the shell.

  •  
    Step 7: Add the 4mmOD tubes and the 1.5mmOD rods as shown.


    Notes: as shown on this picture, the top rods can be longer to cover the whole main chassis length. This is optional.


  • Step 8: Add the CC insert 2 on top of the speaker module, and add the crystal.


  • Step 9: Insert the speaker module + CC insert assembly in the 2nd shell.
    Add the 2 3mmOD rods, and insert everything on the front assembly.

    That’s it, the chassis is pre-assembled and everything fits properly!

CHAPTER 2 – Installing the electronic components – Part 1


  • Start with the Speaker module, which can take 6 single pixels, the kill switch and 28mm bass speaker.


  • Step10: First wire and install the rear pixel. There is a channel for the wires (30 to 32AWG PTFE required)
    Make sure to respect the pixel direction, this is the last one of the chain.


    Step 11: Wire and glue the speaker in place.


    Step 12: Add the Kill switch. The channel is wide enough for 22awg PTFE (make sure to use the smallest OD in that category).
    Then one by one, wire and glue in each pixel in circle (making sure again de respect the direction).
    Testing the install is mandatory at this point.


  • Step 13: Glue the crystal on the CC insert 2. 


    Step 14: Wire the crystal pixel pass all the wires as shown in the dedicated channel.


    Step 15: Then insert the crystal pixel and glue it to the crystal after having tested everything works fine.


  • Step 16: Glue the CC insert 2 on the speaker module and separate the wires so that they will fit properly in both 3mmOD tubes.


    Step 17: Pass the wires into the Shell dedicated holes.

     
    Step 18: For the best lighting effect, you can add frosted plastic on top of the pixels as shown.
    Insert the speaker module into the shell.


    Step 19: 1mmOD rods can be used to secure the assembly.
    A bit of E6000 would also work fine.


    Step 20: Finally, add the 2 3mmOD tubes.

CHAPTER 3 – Installing the electronic components – Part 2

  •  
    Step 21: Add the battery contacts as shown.
    Notes: the switch cover is attached on the positive battery contact slot; It need to be cut way.


  • Step 22: Optional: a series of 5 3mm accent led can be installed on the main chassis.


  • Step 23: Wire and install the OLED screen.

  •  
    Step 24: Glue the crystal on the CC insert 1. Add the insert into the shell.


    Step 25: complete the crystal chamber assembly.


    Step 26: Wire the next crystal pixel and test again.


    Step 27: Glue the pixel on the crystal and insulate the contacts.

CHAPTER 3 – Installing the electronic components – Part 3


  • Step 28: Wire and install the switch on the blade holder. Then insert the blade holder on the main chassis.


  • Step 29: Install the Neopixel connector (or tri-cree led).


  • Step 30: Assemble the blade holder to the main chassis.


    Step 31: Start wiring the soundboard.


    Step 32: There is a slot behind the positive battery contact to solder both the neopixel ledtrip and soundboard positive wires (22awg PTFE).


  • Step 33: Add the crystal chamber assembly and finish wiring the soundboard.


  • Step 34: Add the hex nuts and lock the whole chassis assembly.

    The chassis install is complete!
