New: Grooved 608 bearings

This is the new 608 grooved bearing:

It has an awesome half circle groove which is a perfect fit for the filament.
I use a normal 608 bearing, so it fits to a Wade style filament pusher exactly, like
the Greg's accessible extruder body (thing:8252). Here is a closeup picture:

Here is how the filament would look like on the bearing:

And also a picture with the hyena:

Oh wait, I can do a better photo, to see from the front (notice the match for frame of reference):

Why is it an awesome thing to have?

• It prevents filament twisting
• It is a guide in itself, Accessible Greg's extruder, needs one I believe, at least for me its needed. (accidents happen:-(

Im collecting ideas here. Im recently trying out many methods to raise funds to manufacture the newest gadget for 3D printing world:)

Well, this small improvement may not deserve a full campaign, like the awesome mini hyena, but still what do you think what would be an adequate price for it?

If you have a thought about pricing, or more what price is it worth for you, just put it in the comment. If we can agree on a sane pricing, I will list at that price on the webshop:)

Lets do it folks!

Update:
Some of you were wondering how much flesh rest at the bottom of the groove.
So I destroyed one for ya:)

And here is a better view from the front:

Im not worried about wall thickness here, it is imho pretty strong still.
If you have any other question just shoot it in the comments:)
