On discussion with Vik and how he wanted to setup a place that sells RepRap kits in, and seeing as I needed extruder bits for my RepStrap, I set forth to use the bits from the RepRap Subversion.
There is a big problem with the drawings of the extruder bits, from ease of changing nozzles to a general lack of missing dimensions and also attempting to remove some known problems with them. So here are all the refined versions of them, with two types of nozzles.
The two types are,
Fully machined and have the NT extension (NT means no text, as the first version had text on it, but it became way too expensive to produce, hence the NT version)
Domed nut version.

The domed nut version is very cost effective, and can be purchased virtually anywhere, i've only included the NT version for people to play with if they want, as most people will wan the domed nut version.

You may notice a 0.2mm dimension there, and this was once a proposed future extrusion size. The drill its that need to be bought for it have a short drillable depth of less than 2mm, thus a domed nut version is the way to go for this size of extrusion.

The domed nut nozzle is also cheaper to produce than the MakerBot nozzle.

The parts are designed to make use of local CNC or machining companies or businesses, hence the need for more dimensions.
