Chassis for 2018 hilt version only.
Compatibility with other version is unknown (no information on changes shared by Roman Props)

These designs are no longer supported (FAQ)

Two chassis levels are available for the Roman Inception (Elite or Standard models currently sold by Roman Props):
Padawan for a basic install, with a chassis mainly focused on securing all your electronics
Master for a highly detailed reveal, including crystal chamber parts that can be printed in metal for the best reveal effect.

Both these chassis have 2 variants:
Variant 1 has the “MultiBoards Adaptive Chassis” design which allows any major soundboards to be installed.
NEW design 2018 – Now with MAC-4.0, compatible with ProffieBoard, NB, Prizm5.1 and I3. Updated Crystal Chamber assembly and able to hold a 28mm bass speaker and a pogo-pin connector at the top.
Variant 2 is only compatible with Plecter Labs Crystal Focus 9 and has an additional slot for the Color Extender satellite board.

Additional chassis parts:

For the Master chassis only, here is a list of parts needed to install it:
 4-40 threaded rods x 1
 Hex nuts for 4-40 rods x 2
⇒ Brass or copper rods – 1.5mm max OD
⇒ Brass or copper tube – 4mm OD


Installation instructions: 

– 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: These chassis are for the current version of Roman Inception, elite or standard. There is an old version of this hilt which we never had in hands and thus don’t know if the chassis work with it. We unfortunately cannot provide support for this old Inception model.

Note 230awg 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 3: These instructions will not cover how to wire the soundboard, make sure to learn how to by reading the manual. make sure to test your install along the way! Making sure everything works after important steps is better than having to dismount everything cause something wasn’t wired properly.

Note 4: Given the hilt structure, this install isn’t Beginner level.

Note 5: Recharge port wiring reminder:


Master Chassis Instructions

These instructions were taken from the previous chassis version (< Sept 2018). New chassis install is only slightly different on the crystal chamber assembly. They conver the Master CHassis Variant 1 installation. The Variant 2 or both Variants of the Padawan chassis are more or less similar.

Step 0: Aligning parts. Due to the fact that the parts are not indexed and use a male threaded ring, they can result misaligned when screwed together. Before mounting the chassis, it is mandatory to fix/glue the threaded ring into the clamp section of the hilt so that they won’t move when the parts get unscrewed. This is a rather tricky process, and will take a bit of time to get the part aligned properly (the covertec is a 90° of the clamp box and the grenade groove must also be aligned with the clamp box).

Same method apply for the booster and grenade section parts. Screw the threaded ring in and block it with your finger from inside. Then screw the part, see where it stops, unscrew and rotate the threaded ring, screw the part again, and repeat until it aligns properly.

Once aligned, mark where the threaded ring has to index with the clamp part. Then unscrew it a bit, apply a bit of Loctite glue for threaded parts and let it dry. If when screwing the part back the alignment isn’t perfect, you can also sand a bit the part.

Notes: The chassis is inserted from the back of the booster, then the pommel is added. The female threaded section of the booster has an ID that is smaller than the back of the chassis, so the reveal works by unscrewing the booster + pommel and sliding it back until it gets blocked.

Notes: You can personalize your chassis by painting it, or adding mess, accent leds …etc.

Step 1: Adapt your chassis to the soundboard you want to install

Step 2: Wire your soundboard (following the soundboard manual). Make sure to plan enough wire length, especially for the main led, and CC accent leds, … it is always better to cut the wires shorter, then be too short of wires just to save a bit.

Step 3: (optional) install the RICE Micro JST port. It has to be glued in the chassis (super glue).

Step 4: Wire the recharge port, and the optional kill switch (for the going to the soundboard). Sanding a bit the corner of the on/off switch might be necessary to ensure the booster unscrews properly.

Step 5:  Install the soundboard on the chassis. Tiny drops of super glue will be needed to secure the soundboard on the chassis.

Step 6: Insert the battery (a tiny bit of Super Glue will help secure it as well before adding the CC parts that will lock it in). There is a small channel side of the battery for the wires to pass, and also to allow the SD card to be removed easily.

Step 7: Add the 1.5mm OD rods, cut the to the right length and glue them on the speaker side. You can then clip the cover over the board.

Step 8: Pre-assemble the crystal chamber to measure the right length for the 4-40 threaded rod, and the 4 1.5mm OD rods. If printed in steel, the shell part might also need sanding to house the battery properly and not damage the battery protection (do not force the part over you battery).

Step 9: Important, the main led (and 2nd accent led wires go on the right channel, while the 2st accent led wires go on the left channel as shown in the pictures below:

Step 10: add the rods. 2 hex nuts will be needed on each side of the 4-40 threaded.

Step 11: wire the 1st 5mm accent led and add the crystal to CC Insert 1. Note the channel for the wires in the picture below.

Step 12: Pass the main led and 2nd accent led wires into the Shell 2 part.
UPDATE Sept2018: the crystal chamber uses two 4mmOD tubes instead of the channel part.
Then prepare the CC insert 2 (if the 3D printed crystal is used, it is necessary to glue it on the insert). It is necessary to glue the CC insert 2 on the remaining chassis part (use the rods as temporary guides to do so). Once glued, it can be added to the assembly,  passing the wires in the dedicated channel, and using the 2nd hex nut to lock the parts together.

Step 13: Wire the 2nd 5mm accent led and insert it into the CC insert 2 back.

Step 14: Make sure everything works!

Step 15: Prepare to insert the clamp part, but before it is highly recommended to make the switch hole smoother, so that the wire will slide easily. Pull the switches wires while inserting the clamp.

Notes: to lock the chassis inside the clamp part, we use the star shaped thumb screw. Make sure to unscrew it before inserting the clamp over the chassis. Normally the thumb screw itself is sufficient to secure the chassis (but you can glue a little piece at the tip of the screw to make the lock stronger). When you lock the chassis, make sure it is aligned properly (there is a channel on the side showing were to align the screw.

Notes: the copper mail shouldn’t prevent the chassis from sliding in and out, but if it does, you can sand the inside a bit until it poses no resistance.

Step 16: Add the grenade section (without the neck to make easier to pass the main led wires), then add the neck, then add the heatsink (we have cut and sanded the heatsink shorter on this build FYI) and emitter. Then you can wire the main led and stick is to the heatsink using thermal pad.

Notes: make sure to leave enough slack of wires for the Crystal Chamber reveal. Using 30 awg wires twisted together allow you to unscrew the grenade section and reveal the CC without issues for the wires. To keep things as easy as it can as usual, we don’t use connectors between the chassis and the main led, but one can always enhance the chassis top (using a jack connector or else).

Step 17: Wires the tactile switches. We have drilled and cut 2 windows into the black part of the control box, as shown below. The control box screws maintain the switches in place if the windows are properly placed on the black box, and no glue is needed there.

Congratulations, you build is complete!
