Emergency nozzle done. It’s a rather flat (as opposed to pointy) shape, which gives me nice, smooth surfaces, but it seems to have a bit more lag than the original one.
The nozzle’s bore is 0.35mm, since that’s the smallest size drill i had at hand (i mean, who doesn’t have 0.35mm carbide drills sitting around ;-). By the way, the bore looks pretty ugly if you zoom in, but really, it’s round.

@Sanjay_Mortimer the drawings of the E3D nozzle lack a measurement that tells how deep the large bore goes into the nozzle - that’s the same measurement that would have told me in the first place that’s it’s probably not a good idea to turn down the nozzle further. Can you add a cutaway view to the nozzle’s drawing?

I think the lenght of the small nozzle diameter tube is the direct result of the strange extruder behaviour I was getting here:

This is valuable info that needs further testing.

@Jos_Scheepers it’s a phenomenon known as die swell. This article explains all the things that affect it. http://en.m.wikipedia.org/wiki/Die_swell

I understand that the internet is making it easier and whatnot…but why don’t you invest in a nice set of calipers…I don’t see how anybody can get into 3D printing and NOT have the necessary tools to guarantee success…I understand that you can just come online and ask…but if you just bought a damn set of calipers that not only would you already have your answer…but you would actually be making yourself a better person…

@nikovs_klash_1 , if you read his previous post, his previous nozzle was destroyed…so how are a set of calipers going to help? I assure you, he owns a set. Not to mention, the bore on the inside has a taper, the depth probe on a set of calipers is square, how are you going to get the proper depth against a slanted surface?

Slice gauges…but you gotta have a good paycheck to afford them…as for me…being a Machinist and metal fabricator…I measure the original nozzle before it even gets put into use so that I can fire up my lathe to manufacture new metal parts at the drop of a hat…but I suppose not everybody thinks like a machinist EVEN when they are doing Machinist type work…I am NOT being critical…I am putting a FABRICATORS PERSPECTIVE on a technology that is NOT being dominated by fabricators…A little bit of forthought can save days or weeks of downtime…

@Thomas_Sanladerer All the nozzles adhere to the same basic rule, whereby the small diameter section is 2.5*SmallDiameter.

The remaining section is drilled to 2mm or 3.2mm depending on filament diameter.

So in the case of the 0.4mm default nozzle there is a 1mm long extrusion orifice.

@nikovs_klash_1 don’t be afraid to give some criticism, it’s always appreciated.
So, i do own a couple calipers, but honestly, there was not much that they could have assisted me with. The original nozzle was ruined as is, so i didn’t have much of a choice but to try and get it back into shape - which failed, obviously.
