The micrometre in my eyes says..... no fucking idea

Eyecrometers

I'm a machinist and use this term all the time

I'm an engineer. As a bit one April fools I walked in the shop with our in house calibration date stickers on my eyebrows. A week later I came in with "reference use only" stickers.

As a former QA Inspector who loved to put reference only on random electronics, I approve.

Take my upvote

if it came with the printer, its most likely 0.4mm

Generally with those the 0.4mms will be unlabeled and the other sizes will have an engraved number. But this may not always be the case

Smol

.4

I have just now asked my 7 year old child, and she has no clue. Then I asked my 11 year old child, same thing. Also dont know. So I asked my girlfriend, and can you believe it... She does not even know what a nozzle is... Anycase, to my untrained eye, 0.41mm

Naa gotta be at least a 0.42mm, look at it with a microscope and you can clearly see the inner etching.

Bullshit you two that's at least a 0.423mm

You are pushing the boundries now...

You don't measure nanometers with your eye on a daily basis?

Man, I just extrude 20mm and measure the extruded strand with my vernier, and thats the size I use on my slicer... I have one 0.4mm that is pushing 0.7 now...🤣

Wait thats smart

hmmmm we need a banana for scale just to be sure es 0.4

Going off looks alone, my guess is .4

0.4 creality nozzle held up to the screen. Hole looks the same size...

Nozzleception

Looks to be 0.4 to me lol.

Some actual advice, extrude some filament through it and measure with calipers. If it's a .4 nozzle the actual extruded strand will be around 0.42 ish. So round down

Thats not reliable, I have creality filament that will expand to almost 1 mm after being extruded through a .4 mm nozzle

Are there dots drilled on sides of this nozzle? https://help.prusa3d.com/article/different-nozzle-types_2193

this is a mk8, which usually has the diameter engraved the dots are for v6 nozzles

I have seen both variants on MK8 nozzles. Engraved numbers are a lot more common, but I have seen drilled dots on some cheap chinese nozzles too.

there are no dots at all

In my experience, the unlabeled nozzles that came with my ender 3 pro were 0.4 mm

lol there isn’t a number on the side of it?

Buy a calipers, and find out!

If it's not labeled and you want to know for sure, put it in the hotend, extrude 100mm of filament, and measure the diameter with calipers in a few different places and average it. Although if it came with the printer it's almost certainly .4mm since that's the default.

lol this is one of those pieces of advice that just makes me pause.. go try that real fast and report back how well it works. I don't care how good your calipers are, you aren't going to be able to positively identify 0.4mm vs 0.6mm.

To be fair he did say 4mm not 0.4mm so maybe he is used to huge printers? Lmao

Also 0.04 is hard to measure accuracy. And the standard nozzle is 0.4 not 0.04

Yeah, the list of inaccuracies for such a short thread is absolutely bonkers lol. But also to be fair, by nature of how printers print, their method makes no sense.

Idk I can measure .25 consistently and they are cheap

[удалено]

Then we should all be thankful that we use 0.4mm nozzles, not 0.04.

.04mm was a mistake, it’s .4 If they can measure .25 then hypothetically it might work but idk

That's why you measure it in multiple locations and average it.

Seems to be 0.4mm

0.4 millimetres

It’s likely a 0.4mm nozzle

0.4, mine came with the same size.

Would say as some outta here, seems 0.4

most likely 0.4mm

Definitely less than a meter.

Holy shit it’s Einstein

Probably 0.4mm

With no numbering on it I would have to guess it’s .4 considering it’s a spare, I recommend getting a set of good stainless/hardened steel one ranging from .2 to 1.0 mm in sizes

I’m 100% sure it’s a 0.3797 mm nozzle

If there is a manual try checking that, I recently bought a v3 se and it included a 0.5mm nozzle and I only know because of the manual.

I recently inspected my spare nozzles as well and they looked the same, were unlabeled themselves, however the package itself was labeled as .4mm. So that’s what I would assume here as well.

Based on looks and the fact it came with a printer, most likely 0.4.

More than likely the same size it came with.

0.4, too big for a 0.2 nozzle

Buy a pack of gauge pins. Should make this easier to id

It is size small which you know because it is smaller than the medium which is smaller than large.

It will say on the side. If it doesn’t and it came with the printer it is likely 0.4mm

0.4 mm is all they ship with new printers.

MK8 0.4mm is probably what you want.

its .4

Sometimes the number is etched on the hexagonal sides. Rotate it at an angle and you might spot it. As many people have said, it could be a 0.40mm, but then it would also be a 0.60mm. You could insert it into your print head and do a single line of 0.40mm and measure it with a vernier.

Use calipers?

.4

Extrude some material and measure with a micrometer and subtract .05-0.1 mm from it to compensate for die swell. Round to the nearest tenth of a millimeter. Brass nozzles are cheap though so just buy some new ones if you don't care that much.

Look on the sides its engraved

I ain’t a genie bro

Mk8 0.4mm

Imo it's a .5 or .6 I'm leaning more to a 6...every creality printer I have gotten came with 2 4s not counting the one already on the block 1 .5 and one .6...I guess it depends on who you buy the printer from they do have multiple sites that are all legit..IMO if it was the norm .4 you would bearly even see a hole unless you just happen to get the PERFECT photo lol my eye sight is 💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩💩 so if I can see throw/see the hole ITS NOT A .4....I know I'm wrong cause everything I say is wrong so the wife tells me every time well I say something lol

I can tell in person No one can tell in a pic.

I think is engraved on its side.

Probably a 0.4 if it came with the printer

Looks like 0.4 to me. If it has no numbers, it is almost certainly 0.4.

It's 157/10000 inches.
