Comment

The RSVP MX pen mod was created by Kam with help from UPSB pen modders Nate and Takeshi (adding the RSVP grip in the cap) and Sikkita (removing the barrel writing with an eraser). The pen mod is a continuation of a series of pen mods by Kam that include the RSVP V1, RSVP V2 and the Momentum MX. The Momentum MX is fourth in line after the RSVP MX, but Kam chose the RSVP MX as the final and official penmod of the series because it is easier to make for people.

Stuff needed

Pens

• Pentel RSVP
• Pentel Hybrid Gel Grip (HGG)
• Insert for the barrel (your own or someone elses).
  The official from Kam :

Tools

• Eraser for removing writing on the RSVP barrel
• X-acto knife or some other tool for poking the back cap
• Sand paper or a lighter
• Optional - Teflon tape to wrap around the RSVP tip

Disassembling

1- Take the RSVP. Remove the cap, back plug, grip and ink tube.
2- Take the HGG. Remove the tip and grip.

Tutorial

Step 1

Remove the clip of the cap and use the sandpaper/lighter to round off the stub.

Step 2

Poke a hole in the back plug, stick the ink tube in reversed, place back onto the RSVP barrel.

Step 3

Stick the RSVP grip inside the cap to add weight to the back.
Important : put the grip in far enough so that the edge of the cap goes at least 1~2mm past the back plug when placed on the pen. This greatly reduces the chances of breaking the pen, without any noticeable change in how the pen spin.

Step 4

Screw the metal HGG tip onto the plastic RSVP tip.
(Optional). Wrap teflon tape around the plastic RSVP tip before putting on the metal HGG tip. This will help hold the metal tip, but is not needed.

Step 5

Slide the HGG grip over the tip and front of the RSVP barrel to replace the missing RSVP grip. The grip may not align perfectly with the metal tip, but the grip will stretch with some use.

How to improve the aesthetic

Tip no.1

Use an eraser to rub off the writing on the RSVP barrel. The fine size ink with Silver writing is much easier to remove than the medium size ink with Gold writing.
To reduce the chances of scratching the barrel, you can dip the eraser in rubbing alcohol or water.
This will take longer to erase, but it will keep your pen cleaner.

Tip no.2

Design or download an insert online, print it.
Insert dimensions for RSVP barrel insert: 8.8 cm x 3.81 cm
The height of the insert is twice the size that is needed, this is only to help in rolling the insert.
Once an insert is printed, take out the back plug and ink tube from the RSVP. Roll the insert using the ink tube and slide it into the barrel.
Once in, use the ink tube to adjust the position if the insert gets misaligned.
Replace the ink tube and back plug.
