Just throwing this idea out there, but once we have the dimensions for the pen, someone should make and sell an expansion card that has a clip for the pen. You’d have to print (or mold) it in a soft plastic or have spring steel to keep it durable. Maybe polypropylene or a hard-ish TPU.
Here’s a simple sketch of what I’m thinking about.
Maybe a drawer with a clip? You could store extra pen tips in the drawer!
That would be a possibility!
Magnetic attachment would also be very cool. I mean that wont be as secure, and you need to be careful with magnets and computers, but it would be my preferred solution. However, a clip holder would also be good, especially if it could be on a storage expansion card. In that way you are not giving up a USB C port for nothing.
I agree that a magnetic solution would be more elegant to look at, but I don’t think it would work if you want to put the laptop in a bag.
You could have the clip positioned such that in between the two (or maybe 3-4) clipping bits the USB-C port is still accessable.
maybe a storage card so it isn’t a wasted IO slot?
or, you could have a male usb-c connecter so it can charge while it is clipped in
Ooh, I think that’s the best idea so far.
it would be pretty breakable though, so I wouldn’t get my hopes up about the idea unless we could find a usb-c port with no retention force and then put it on a ribbon cable so if something pulled it away the USB-C charger would just pull out. (we could call it clipsafe 
)
Why not get one of those magnetic USB-C adapters, one end would be installed in the clip card, the other you just plug into the pen? It wouldn’t be enough on it’s own to hold the pen in place, but it would solve the snapping male end problem.
This is a bit of an old thread, but this has been banging around my head as well.
Not with a plastic clip though, with a fabric one, like the elasticated fabric loops that hang off the side of notebooks.
Personally I was thinking of making one up with a red heavy duty webbing or something similar.
You would need to have two clips, one at the top and one at the bottom of the card I think. You could then also use that port as the charging port when working at a desk.
a magnetic solution seems to be the most ideal to me, a clip is too fragile, and if you look at existing ipad/surface tablet cases, they typically use a little trench to retain a stylus.
It is a bit disappointing that at the price point of the framework 12, they didn’t include some internal magnets in the chassis for this purchase.
A possibility that just occurred to me: “dummy” USB-C or USB-A plugs with a clip on the end for the pen. They could slot into the socket with some durable but non-conductive plastic, and the user could unplug the pen when using it. The loop could either be a solid circle that the pen slid in and out of, or a broken circle to allow the pen to clip in and out. If the fit were firm enough, the pen should not fall out, and it would allow a functional USB-C or USB-A card to remain in the machine.
something similar to this 3d model i was using back with my old thinkpad would probably work for this, it let you hold the pen sideways, or set it tip down for easy grabbing
I just got a metapen m2 today, it actually snaps right to the input cover magnets. I wouldn’t trust it too much but it seems sturdy enough for just carrying the laptop around.
there’s actually an empty spot on the bottom case that a magnet could go in, i’m trying to source the right size magnet, if i can find one my pen would stick right there without an issue.
Oh that would be perfect!
There is no metal part inside the pen for magnet to hold the pen,
For those following this, it looks like someone has begun the process of actually making one of these such clips: FWL12 styus holder
