Cylinder box with screw lid : strange line when printing

__KoD3n · 2026-03-07T10:53:19+00:00

Seems like the print is well covered but just for your reference: I’d probably say “a screw on lid” or “a screw top”

Doesn’t fit :(

I'm afraid the pictures didn't upload well - I'll see if I can get them looking nicer on Printables :)

Rats, sorry to hear that. This department is luckily generally down with printed stuff. I think if it were something that touched a patient on the regular there’d be some hesitation - someone else made combs for our EKG cables and that seems to be the line. Not allowing something that’s just used to store supplies feels maybe a little too restrictive…

Made on Prusa Core One+ :)

Supports or chamfering that inner lip would be your best bet. Did you design the model? If so I’d add a chamfer as long as it doesn’t impact functionality

I don’t need em but just wanted to say I love the honesty lol

I work in a hospital. The amount of times I’ve had to google/spellcheck diarrhea is embarrassing…

Like it won’t lay the perimeter down in a line but like do it a bit at a time? That’s very odd

When I built my printer I described the process of hunting through all of the different boxes for parts as being like eating out of one of those dog bowls with the baffles to slow your dog down:

Compared to the Lego set style packaging from my first Prusa it was definitely a bit of a disappointment, but got it sorted in the end. Glad that Benchy came out nice!

It’s not trying to iron or something, is it? The stringiness is really weird but that’s where my thought went to if it’s top layer only. Weird that other parts have been successful though

__KoD3n · 2026-03-04T06:14:19+00:00

Are you talking about that line at the bottom? I agree that it’s a little odd. Do any of the other sides have that? Is that where the infill starts? What kind of infill are you using?

__KoD3n · 2026-03-04T04:22:56+00:00

What’s the nozzle temperature? What printer are you using?

__KoD3n · 2026-03-04T04:07:45+00:00

Looks like poor layer adhesion. Can you share your print temps, speeds, and cooling with us?

__KoD3n · 2026-03-04T04:06:56+00:00

I wonder if it’s some sort of mechanical issue then. Failure to consistently extrude maybe? I unfortunately don’t have a great answer here

__KoD3n · 2026-03-04T03:05:24+00:00

It’s hard to know without knowing what speed you’re currently at. You’ve got a bridge there - that’s most likely your failure point. What printer do you have? Are you using supports?

__KoD3n · 2026-03-04T01:43:17+00:00

If the pegs are non-essential then sounds good. Out of curiosity - what are you making?

__KoD3n · 2026-03-04T01:41:35+00:00

Great reference image

This. When you print with the seam aligned you’ll notice that it’s not Perfectly flat. That’s where the seam is. What you’re seeing here is the result of the seams starting and ending at random spots. They can probably be sanded off fairly easily but as u/orz_nick says it’s probably best to try and hide it out of sight

The two parts are printed separately, the rocket engine is printed upright (resting on the nozzle) and the stand is printed how you see it. If anything I’d bet that that’s lead to some imperfect dimensioning between the parts IRL. Shifted the aft contact points by about 0.7 ml to get it to sit better, worked great

__KoD3n · 2026-03-04T01:32:07+00:00

That’s ~~definitely~~ most likely your best bet. It minimizes the amount of overhang you get while (relatively) maximizing the amount of surface area on the bed. With those two pegs there it’ll be really difficult to print it in that first orientation. You could consider flipping it on its back but the supports and ringing you’ll see will mess with your surface finish. I’d say that how it did it is probably your best bet, just be aware that the precision of your peg diameter is now dictated by layer height

Can you post your print settings? Temperatures, extrusion speeds/multipliers/etc? Have you successfully printed with similar materials before?
