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!
Here is a list of parts needed to install the Chassis
⇒ 1.5mmOD rods for the soundboard cover

3- DIY empty hilts:

 Available on Roman Props 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 to the high end Crystal Focus.
Naigon Elelctronic Creations – from the entry level Spark 3 to the high end I3.
Padawan Var1 – Single 21700
Padawan Var2 – Single 18500 for NB install,  Single 18350 for other soundboards.
⇒ Recharge Port, 1.3mm port is used on this chassis
 Main Led, Tri-Cree XPE-2 recommended
 Switches, tactile switches to be installed under the clamp card using the support included in the chassis kit.
Padawan Var1 – 31mm Bass speaker or 28mm Bass speaker (Ex: Saber Essentials), or 28mm flat Railmaster.
Padawan Var2 – 28mm Bass Speaker (NB install only) or 28mm flat Railmaster (for other soundboards).
 Accent Leds, 3mm or 5mm leds can be added. They can be found in any electronic shops.
 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).
 RICE, optional, all chassis have a slot for micro-JST female plug for a RICE to be installed with Plecter Labs Soundboards => Micro-JST can be found on Ebay.
 On / Off Switch, mandatory to switch off the soundboard, Ex: The Saber Armory
 Blade 1″

Quick install guide:

(step by step)

– 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: Use the smallest AWG wire size possible:
– Tri-Cree install => 30awg for eveything
– Neopixel install (Var1 only) => 32 awg wires for everything except Battery and Neopixel strip + and – (24awg PTFE).

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

Padawan VAR1

Step 0: Choose your speaker, you can either install a 28mm speaker using the adapter part provided with the kit or Saber Essential 31mm speaker, directly attached to the soundboard module.

Step 1: Wire + install the main led

Step 2: Install the battery in the battery module (and CEx if used), insert the battery module in the grenade section (passing the led wires over it), and lock the whole by screwing the clamp spacer.
Notes: there are 2 chassis parts going in the clamp spacer: one to channel the wires to be installed on top (and avoid conflicts with the speaker), one to add the hex nuts, on the side.

Step 3: Wire and install the soundboard, recharge port and on/off switch in the soundboard module, then add the cover. The soundboard module will normally press fit into the clamp spacer, if not totally secure, you can either glue it or add electrical tape.

Step 4: Add the speaker and wire it. The speaker has to be glued to the soundboard module (super glue). If using a 31mm speaker, the clamp spacer parts have a groove to provide additional support.

Step 5: Assemble back the hilt, then wire and install the clamp switches holder.

Padawan VAR2

Step 1: Install the soundboard, 1.3mm recharge port and kill switch.

Step 2: Due to lack of space, only small batteries can be used with Rudy Pando’s chamber.
The cover is held with 1.5mmOD rods.

Step 3: The speaker is held by 2 parts. Assembly require super glue to secure everything together.
According the the battery used, a flat or bass speaker is to be selected. There are 2 different slots for either one or the other.

Step 4: Add the soundboard chassis. Make sure the battery doesn’t touch the speaker and close.
