SHOTO Chassis

Part1 – Main chassis kit (recommended in black plastic): kr-ahsoka-shoto-part1-main
 Part2 – Optional Crystal Chamber insert (recommended in raw brass): kr-ahsoka-shoto-part2-cc
Optional Crystal (recommended in Ultra Frosted): kr-ahsoka-shoto-part3-crystal

Switch Drill Template:

Optional part – If you need to drill a second switch hole (only required for soundboard needing an auxiliary switch), this drill template will match with the switches holder included in both main chassis kit: kr-ahsoka-aux-switch-drill-template

Additional chassis parts:

 Brass or copper rods – 1.5mm max OD

Installation instructions:

(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: 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:

Note 5: Both Shoto and Shien chassis are quite similar in their install with only a few particularities. These instructions cover the Shoto chassis install.


Step 1: Cut enough length of wires for the main led and switches.

Step 2: Install the 18500  (Shoto) or 18650 (Shien) battery in the dedicated slot, place the main led and switches wires on top of the battery, then add the battery cover. The 1.5mm will lock the cover in place and secure the battery.

Step 3 – Optional: If you have chosen to install the optional Crystal Chamber parts, insert the 5mm accent led in the 3D printed crystal (sand the led to make it fit completely in the crystal). Then insert the crystal into the CC part. The wires go through a dedicated hole under the crystal chamber part and then you can glue the part to the chassis body to secure it.

Step 4: Wire and install the 20mm speaker. The speaker holder area also has a hole for the wires.

Step 5 – Optional: To make it easier to disconnect the chassis from the recharge port (make easier to take the chassis out to access the SD card for example), you can add a micro JST in the slot indicated below:

Step 6: Install the soundboard

Step 7: Take the blade holder out, pass the main led wires through it, then wire and install the main led into it. Screw the led holder back to the main body.

Step 8: Wire and install the switch(es) in their dedicated chassis part, using the switch(es) wires.. There is another little part that goes over the switch(es) to lock it in place.

Step 9: Wire the recharge port to a male micro JST (if used this optional method, or directly to the battery/soudboard). Make sure that the recharge port leads are cut to the minimum needed to save space. Screw the recharge port in the main bode and connect it to the chassis.

Step 10: Place the chassis into the main body. Note that the Shien chassis has an additional part that can be used to secure the black grooved part and avoid it to rattle.
