– Name : 41RFLOW G3 mod (Airflow G3)

– Creator : Vôre-Tèx

– Length : 20 cm

– Weight : 14g

– Insert : Yes

– Weblink : /

– Difficulty : Medium

– Stuff :
– 1 Pilot G3 (Metal ver.) (Everything but the inktube)
– 1 Patterned G2 (also known as Fashion G2) (Grip, Back barrel) (note : the patterned barrel is important, so you won’t have to sand too much of the G3 barrel) (normal G2 barrel is fine, but if you plan to use an insert under the barrel, you will need to sand more of the G3 front, which would make the mod more fragile)
– 1 Uni-ball Signo DX (Grip, Tip)

– Stuff price : Less than 10 USD.
.

– Tutorial :

1- Prepare the front of your G3 :
a) Cut as shown: part with holes, smooth part, 4 blocks, 2 blocks
b) Remove the part with the holes

1- Remove the little squares (with a nail clipper) before removing the grip.
Note: because it is better to not stretch the G3 grip for what we need to do after.

If you’re using an X-acto knife and if you’re right handed:
a) both thumbs should push the blade;
b) use the right index finger as a guide (at the same time to moderate the strength from the thumbs (to avoid to cutting the grip) and orientate the cut)
c) 1,2,3,4 from the left hand to hold the G3 barrel

2- G2 barrel :
a) Cut 4.9cm from the back
b) You should notice a little bump at the middle of the clear G2 barrel (above the red line, there is a small reflection from my lamp). When the G3 front barrel is inside the G2 barrel, it must not go further than this bump, because from this point onwards the G2 barrel is getting thinner.

G3 barrel :
a) Thus, cut the G3 front barrel at the red line (1.8cm)
b) Remove the grips carefully. Do not stretch it.
b) Sand the G3 front barrel (not too much otherwise you’ll need to add some clear tape to hold the G2 barrel securely), BUT do not sand/file the 2mm part where the star is (at the left). We need this part clean to make the mod strong.

3- Cut the G2 and DX (2.2cm) grips as shown.
Prepare the G3 cap, remove the small rubber stopper and the clip.

4- Prepare the G2 barrel as shown. Ultra-optional thing, you can add any metal/silicon ring like below.

Use the smooth part of the G3 grip to link the Signo tip to the G2 barrel.

Add the 2 stripes portion of the G3 grip (originally at the front of the pen) to the back of the G3 front

Note : This detail is to make it “perfect”, since the first stripe of the G3 grip is a little bit thinner than the other stripes. Since you left the small plastic bump at the back of the G3 front, there won’t be any shift between the G3 barrel and the small G3 grip we added if you use the front stripe of G3 grip (you’ll get that shift if you use another G3 grip sections).

5- Remove 1mm of the DX grip as shown. (it allows you to put an insert in the cap)

6- Take the G3 backplug and add the rubber stopper inside:

7- Prepare the cap :
G3 tip < G3 grip < step 6 ” =] “< DX grip and put the leftover G2 grip onto the cap

8- Add insert in the cap and in the barrel, with some tape at the back of the G3.

9- Finish by adding some leftover grip rings at the front (in the G3) or at the back (in the DX grip) to make the pen as perfectly balanced as possible for your taste.

– Comment :
An ambitious project I’ve got there, at the beginning of the year 2018 : create a F1r3fly G3 mod (that’s to say single capped, with the same aesthetic and balanced), but lighter and stronger, with as little pens as possible.
I am pretty proud of this pen mod. I spent a lot of time to design it especially the front.
Hope you guys will appreciate it as well =)
