The morality of this article is debatable, so its author remains anonymous.
This article analyses the two mods whose tutorials have been kept secret on the Menowa* membership. This article is NOT a leak. All information presented can be found publicly (or with media archives formally being shown publicly).
Modrodmod
Firstly, all parts can be found in the description of the video
Let's look at each one:
The g-2 seems to be included with Supergrip since both are similar. Both aren't cut.
For the Tect and Dr.grip, we will see that from another source, the same for the G-3.
The following part will be off-topic, but an important one. On YouTube, when you try to upload a video, YouTube automatically generates 3 random thumbnails out of moments of your video. You later have the option to upload one yourself.
But, if you use a 3rd party website like this one and enter the URL of the video in it, you will be able to obtain the actual and automatically generated one. This means that some screenshots of Menowa*'s mod are possible to find outside of the video itself.
By applying that process you can get some info.
The pictures are in very low resolution, but it's enough to determine that Tect refers to its Tip, Dr.Grip refers to its metal ring, and G-3 to its grips (3 stripes).
For the tip structure, we will look at one of his old vine video:
As the big tip isn't in the description part, we can guess the only tip stack was Tect tips, Dg rin,g, and G3 stripes.
It is reasonable to assume Menowa* presented these as "random grips" (this means the grips aren't in the description). The black grip is undeniably Anyball (the 3 first blocks) and the other is a random white grip cut the length of 3 Anyball stripes. Maybe Signo Broad as it is also a flat grip.
For the insert, it was found by Tache in this tweet.
Finally, the structure:
1st layer:
G2 grip, Signo broad grip, 3 stripes of Anyball.
2nd layer (all of the 3 first parts are covered by the G2 grip)
Tect tip -> Dr.grip ring X tect tip -> Modrod barrel
3rd layer
G3 grip (3 stripes) (inside the Dr.grip ring) and insert inside the Modrod barrel.
Buster DEX
Similarly to the Modrodmod, the list of the parts can be found in the description.
"DEX
comssa
Airfit
Juice up
Lakubo"
By also doing the "Thumbnail method", we see 2 things: The back of the DEX is filed inside and the lakubo backplug is inserted inside it.
the part list look now like this:
DEX x1 (barrel)
comssa x2 (caps)
Airfit x2 (grips)
Juice up x2 (tips)
Lakubo x1 (backplug)
O-rings x2 (not specified but shown)
By doing some tests it seems like the Comssa caps were shortened by 0.5cm and the Airfit grip cut to around 3cm.
Structure:
Onto the comssa cap:
2 o-ring -> 3cm Airfit grip -> Juice up tip inside the Airfit grip
And the other comssa cap is being held by a lakubo backplug.
