Parts Details:

1- 3D printed Chassis parts:

Shapeways Shop Section ⇒ C7 – Korbanth

Three chassis levels are available for the Parks / Korbanth K4 saber Kit:
Padawan for a basic install, with 2 variants and chassis mainly focused on securing all your electronics.
Knight for an All.In.One chassis including a crystal chamber reveal by unscrewing the booster/pommel section.
Master for a crystal chamber part that can be printed in metal and revealed by unscrewing the booster/pommel section.

These chassis can hold a Nano Biscotte, Prizm 5.1 or I2/SPark2.

Variant 1 uses the speaker / recharge cone design, to access the recharge port / kill key by unscrewing the pommel.
 Chassis Var1: korbanth-parks-k4-padawan-all-in-one-var1
Variant 2 has the speaker at the end. It uses an on/off switch instead of a kill key, and both switch and recharge port are accessible by unscrewing the booster/pommel parts.
 Chassis Var2: korbanth-parks-k4-padawan-all-in-one-var2

2- Additional chassis parts:

Most of the chassis parts needed for our chassis are available at The Saber Armory.
Local hobby stores or online store (as well as eBay) are a good source for parts.
You can also be inventive and add any custom parts, wire mesh, paint job or else to your chassis to give it an unique look!
 Brass or copper rods – 1.5mm max OD.

3- DIY empty hilts:”

 Available on Korbanth website

4– Electronic components and blades:
Saber electronic components are basically more or less similar from one saber to another. You’ll need a main Led, a Battery, a recharge port, one or two switches, a soundboard, accent leds, a speaker and wires. Then the blade is the last part of your saber, they are usually made from PolyCarbonate tubes + tip.
You can find most of what you’ll need at The Saber Armory. Some components can also be found at The Saber Bay on Etsy. Local electronic shops or online stores like Digikey are also a good source.

Soundboard, the “heart” of our sabers is the Soundboard, here are the 2 major Soundboard producers:
Plecter Labs – from the entry level Nano Biscotte or Prizm 5.1 (recommended).
Naigon Elelctronic Creations – from the entry level Spark 2 to the high end I2.
Battery, 18650 battery 
⇒ Recharge Port, 2.1mm port (kill key included in the Master and Padwan Var1).
 Battery charger, according to the battery voltage used.
 Main Led, Tri-Cree XPE-2 recommended
 Switches are probided with the hilt.
 On / Off Switch (Padawan Var2) – slider switch (example).
 Speaker, 20mm Speaker
 Accent Leds, 5mm led for the Crystal Chamber recommended on the master chassis (if RGB, read your soundboard manual to select between common anode or common cathode led), 3mm leds for the others.
 Wires, we strongly recommend PTFE wires, as the insulation is thin while still able to handle current very well. You can find them from this eBay shop for example. Use the smallest AWG size possible:
– Tri-Cree install => 30awg for eveything
– Neopixel install => 32 awg wires for everything except Battery and Neopixel strip + and – (24awg PTFE).
 Heat shrink tubing, to protect your joints.
 RICE port 
– a RICE port can be added with a micro jst port. Ex on ebay.
 7/8″ Heat sink.
 7/8″ OD Blades.

Quick Install Guide:

– These instructions will details the install procedure as much as possible. GOTH-3Designs cannot be held responsible for any mistakes made by DIYers.
– Always wear protective gear when working on install (gloves, eye protection, …), GOTH-3Designs cannot be held responsible in case of accident.

Note 1: 30awg wires and smaller are mandatory for this install (30awg for main wires and 32awg  for accent leds and switches are highly recommended)…. Oh and definitely use colored wires to make your life easier.

Note 2: These instructions will not cover how to wire the soundboard, make sure to learn how to by reading the manual.

Note 3: Recharge port wiring reminder:

Master Chassis:

Install is similar with the Knight and Padawan chassis.
There are 2 covers on the chassis (soundboard area covers) that come already attached, they need to be cut away and will eventually be added back and help by the 1.5mmOD rods.

Pass the led wires before inserting the 18650 battery. Make sure the led wires are not stuck and can slide in the channel.

The soundboard are installed with the SD facing down. NB can be installed by default. For Prizm 5.1, the NB support needs to be removed. For I3 and equivalent NEC boards (trudrive needs to be removed and installed on top or under), both the NB and Prizm5.1 supports need to be cut and removed.

There is a dedicated channel under the Crystal Chamber part for the crystal led, speaker and recharge port wires to pass through.

Wire and install the recharge port first, then add the 20mm speaker. Pass the recharge port over the speaker and add / glue the speaker cover on top.

Install the led into the crystal, then add the chamber to the chassis (pull the wires to leave space for the CC to insert properly).

Add the covers and glue the 1.5mmOD rods to secure the chassis assembly. You can add accent leds on the Soundboard cover to light through the bubble strip.

Once inserted into the hilt the switches wires are pull from the side and wired to the switches.
Leave enough slack on the side of the chassis to allow it to slide down for SD access.
