the ergonomic s move is a great pen, it fit sthe hand lovely.
It's a shame that the actual roller ball pen is so bad.
So this is how to fit a Bic Fine line (a personal favourite) instead.
Step 1: It's a Nice Pen But
this is the ergonomic stabilo "s move" it comes in a specific left hand and right hand configuration.
It's very comfortable....but
Step 2: The Rotten Refill
good gravy who picked that as the refill?
It's a really primitve rollerball.
And to make matters worse, this one is blue!
Step 3: Make a New Refill From a Bic Fineline
It is nothing to look at but the Bic fine line does a really good variety of strokes.
I'am a professional artist and despite the number of pens I use, one of these blighters is never out of my hand.
But it's way too long to fit here.
Junior Hacksaw please.
Step 4: Sawn Off
pop the lid, take out the refill and the black plastic bung at the other end.
Now measure back from the front 31.5mm and saw the blighter off.
Step 5: How Much Ink Can You Fit on the Head of a Pin?
now all ballpoints have the little gap between the level of the ink and the end of the tube.
So scoop out some with a pinhead.
I do not know why but when I didn't do this there was ink all over the place.
could be surface tension,air pressure or room for heat expansion I can not say.
Step 6: Bung It Back In
This black plastic bung needs a bit of filing to fit as the shortened barrel is a little narrower.
it's pretty much trial and error.
And if you split the barrel then just super glue the thing together.
Step 7: Pop It All Together
put the shortened barrel and refill together
Step 8: Nearly Done
then pop the mini Bic back into the stabilo and put it back together
Step 9: And There You Go
there you have a stabilo s move with a custom cut refill tube into which you need only snip down any bic ball in to fit.
I know it isn't very complex but I am only really posting this as I was doing this on the day I found instructables.
It seemed appropriate.
