Hi, here's finally my tut for the Flexible MPMX Writable. It\\\'s the 2nd version of the RSVP MPMX Ballpoint which was sadly unstable.
Why Felxible MPMX Ballpoint? Flexible, because the body is a Comssa\\\'s, MP because of the Mechanical Pencil, MX Because of its singlecapped style, Ballpoint because of its Ballpoint writing possibility.
First of all, some pics
The whole Pen :
Its MP function :
It\\\'s Ballpoint function :
The mats :
A Comssa Body, a Gripmatic, a Mini-RSVP inktube, a HGG inktube, a RSVP or mini RSVP cap, the Anyball clickpart, Anyball grips and a match (not on the pic).
The tutorial
I recommand reading the whole tutorial first because it\\\'s pretty complicated^^
1. Take the Comssa Body, take off the Backplug and the inktube. Make the litle whole on the Comssa Tip as big as you can put the tip of the mini rsvp through
2. Sand down the RSVP clip and cut the cap off just under the litte ball.
.
3. Disassemble the Anyball, Take the Anyball clickpart. Take the HGG inktube, empty it and cut off the tip. Cut of a piece of the empty inktube that fits in the Anyball clickpart. Cut now off a piece of the body of the match that fills into the HGG inktube. If it doesn\\\'t hold together, you can use some Tape. Take care that the match body sticks up a bit or that it\\\'s at least at the same level that the clickpart and the inktube.

4.Take the Mini-RSVP inktube, cut it off a bit under point where the ink stops (where the scissors are in the pic). Plug it now with a toothpick in order to prevent the ink from leaking.

5.Take now the rest of the empty HGG inktube and put it as far on the Mini-RSVP inktube as possible. Cut the other side now off in order that the whole thing mesures ~12,7cm.

6. Dissasemble the gripmatic, cut it off where the grip used to end. Take care, you have to cut around in order not destroy the mechanism.

7. Cut the white part now off 5mm above where you just cutted.

8. Sand down the green part of the GM so that it fits into the Comssa.

9.Make the whole bigger where you cutted off the white part of the GM so that the HGG inktube fits into the first 2-3 mm of it.

11. It should be assembled that way :

Finetuning
It's a pretty complex pen where every part has to be perfect-sized in order to guarantee a good working. If your mechanism doesn\\\'t work yet, you should try to modify some aspects of the Pen.
The GM part falls easily out of the Comssa body, what should I do?
12.Sand down the green part of the GM again in order to get a tinyer fall. Remove the little bumps inside the Comssa body with a scissor :

The Anyball grips move easily, what should I do?
13. Put some tape around the GM part.
The RSVP cap doesn't hold on the Comssa Body properly, what should I do?
14.Sand down a little the red marked zone with some very fine sandpaper. You can also try to put a little bit of Tape around, but I don\\\'t recommend doing this.

Now the whole mechanism doesn't work anymore, what should I do?
15.If the MP refill doesn't come out, you may trying to shorten the HGG inktube a bit. If the RSVP cap jumps of if you press on the clickpart, you may shorten it a bit like it's shown on the following pic :

Comments :
Gripmatics are awaidable in France, China, Germany and some other countries.
The mod doesn't make any noise spining.
Its weight is comparable to a MX².
The length of the mod is 17,9 cm without measuring the clickpart and 19,4 when you do so.
Without counting the clickpart, COP=COG with an imprecision of some mms (2-3). You can make it perfect shortening a bit the Comssa Body.
You can also use a reguar RSVP inktube but if you don't want to cut into the part with the ink, there won't be any place for the MP refills!
I'd love to get some comments on my mod and tut.

I can't see some of the pictures for some reason. The links dont seem to be working.
Great mod and tut though, I might try making it sometime. I need to get myself a gripmatic.
What's the match for? -

It's pretty cool seeing something else than the standard stuff.
I can see this definitely being a school pen if you make this fully black.
I've never been a fan of retractable/mp mods for spinning, but for school this seems pretty good.
Personally, I think you should ditch the anyballs on the back..they look a bit tacky.

Pics fixed^^ The match is for filling the Anyball clickpart in order that it's capable of pressing down the Tip of the Mini-RSVP inktube.
€dit : @Imatt, you can modd it that way :
and push out the MP that way :
but it's way more time-consuming. -

Woah, good tutorial and mod, chris512!
I really want to make this, but I dont have a GM mech.
edit: shouldnt this go in pending tutorials? o-o -

lol tuts go here http://www.upsb.info/forum/index.php?showforum=78
it looks nice, but i think that the gripmatic tip would make it pretty front heavy =\ -
Date: Sun, Jun 7 2009 19:26:48
Ups, sorry can anyone move it plz?
If you do like in the tut there is just 2-3 mm difference betweem the COP and the COG. Anyway, you can adjust it cutting a little piece of the Comssa Body. -

Can we use anything instead of that rsvp inktube? I really don't want any leaking cuz I find that toothpicks aren't enough to hold the ink sometimes
