Split it with desktop CNC router and double flute end mill. Sanded it afterwards with 1500 grit sandpaper.
What CNC machine are you using? How does it perform? That's going to be my next investment, though I'm pretty set on one of these: https://www.kickstarter.com/projects/boxzy/boxzy-rapid-change-fablab-mill-laser-engraver-3d-p?ref=nav_search
I have a small homemade router with lead screws, plastic bushings and a 100W Proxxon, Not sufficient to my needs so I am building a new one.
I bought a kit for this one a week ago:

About BoXZY:
7" x 7" footprint is pretty small and I highly doubt that NEMA 17 motors can deal with aluminium at higher speeds. I think you can get a bigger and better machine for that price.
There is a man from Toronto who makes nice CNC routers. He promises that he will launch a Kickstarter project soon: https://www.facebook.com/xzerocnc.routers?fref=ts
Here is the new nozzle I've just measured. Drilled with 3.45 drillbit - bore came out 3.47mm. It has to expand for 0.03mm due to the heat.
Sam - a caliper is really not the best way to measure a hole diameter if you want an accurate determination, especially for a hole that small. I'd guess that your determination is on the small side, though the error may not be significant for your purpose.
On my spare nozzle, I get 3.49+mm with a gage pin and 3.50 with a hole (ball) gauge.
I used Imperial gage pins and the 0.138" pin fit, but the 0.139" pin didn't so the hole diameter is somewhere between those dimensions.

LabRat - have you looked at Tormach CNC mills? It's a lot more money than the KS 3-in-1 machine, but much better if you are serious about machining.
I have their larger model and am getting ready to buy their CNC lathe.

I appreciate the link, but that is QUITE a bit more than I'm capable of being able to afford (grad student). Also, my primary goal with it would be circuit boards so I can stop wasting my time and money with chemical etching. I imagine that I would start playing around with some light aluminum machining, but nothing too ambitious (at least for a while). After I graduate and get a job I might end up getting something like that.
Not sure what you are looking to spend but I have a Taig mill.. Not too bad but still some $$$
You can always look at Sherline too.. I have one of their lathes.. Just manual not CNC..
That sucks! I just looked at my other nozzle and its the old one so won't work with my new hot end. I will have to switch out the hot end if i want to use it. :o
Dammit!
Why would it not work with newer version of hot end?

From the pic you posted I thought it looked like the thread was more cars on the old nozzle. I am going to go pull the new one out and compare it now.
Update- My bad. It was an optical illusion. ha The old nozzle works just fine. Great! Time for some ...... hehehe
Thanks Sam, I was just too lazy to try it and relied on the pic, I thought I counted 5 threads on one and 4 on the other. :o
Sam, did you remove the dimensioned drawing?
NVM, just saw that you changed it to an updated version. Thanks!

It's right above this post..
Anyone have success rounding out the “afteemarket” nozzles? My nozzle got messed up due to carelessness and in need of a nozzle but Zortax store is out of stock. I have the emergency nozzle they sent with the printer but it has a flat top like the afina nozzles.
I’m guessing it’s not a huge deal but I do like the prints I get with the regular nozzle and until they come in stock I figured I can round out the top a bit on the other nozzle to keep the quality.
Any insights?
Thanks
I think (but am not 100% sure) that the main purpose of the rounded tip is to make the electrical height sensing more accurate. Not sure that is has much if any actual affect on print quality once that's past.
Thanks Julia. I will try before I round it. They seem to be the same. Will find out shortly, lol
Might want to try some of the re-sellers, Some of us keep spares in stock that we do not have listed yet. I know I just received the parts list with pricing for internal use, so we are getting close to having the the full stock listed online. Give our support a call and see if you can get any nozzles.
-Michael
Yeah. I checked all resellers and none on site so I got email from Zortrax as it was a computer glitch that the Z site didnt have any nozzles.
I jut ordered one from Zortrax and while I was there I restocked my Zabs Black. lol
I do have 2 pack nozzles coming from Octave but they are to test as they are not my favorite Zs. lol
Hopefully they will work just fine and I will have some back ups.
I currently am printing an order with my Emergency nozzle and it seems to be doing just fine.
Well I have a Zortrax nozzle on the way but tested with an Afina nozzle. It did well. Needed the top opening widen a bit to fit around the hot end filament tube but a 9/64 worked perfectly.
Still think Zortrax prints better but will work if ever needed to.
Heres the test print at regular .19 ZABS
Maybe it's just me, but that print looks like it has two different layer heights. :huh:
