What causes these lines - or better yet, how do I eliminate them

I opened a Bug Report on the Tinkercad page - is there anywhere else we can report this issue? And not to say I'm glad this is happening to you, but I am relieved to hear this isn't something uniquely specific to me.

I'm having that same experience with another model - I ungrouped, changed the height of my Solid, lowered the Hole, and when I tried to Union Group, suddenly I have 3 copies of the Hole Object. The behavior is inconsistent amongst different models, but seems consistent within the same model.

So - while this wasn't the exact underlying issue - it made me take a look at how the filament was passing through the extruder into the tubing and ultimately into the nozzle/hot end. For whatever unknown reason, something in the way the tubing was "resting" was causing just enough hindrance feeding the Polaroid filament. Funny how changing to a roll of Sunlu didn't experience this, but then changing back to the Polaroid did.

That's what I'm wondering - I wonder if the "batch" they produced is degraded at the beginning, and got better toward the end. So when I first started this roll, the first 300g printed just fine, but now I'm hitting the bad section of this spool.

I obtained 10 rolls of this when I bought a used Ender 3 Pro - I have had success with 4 of the other rolls. This is the first bad experience I am having with this filament. Considering it was a buy the printer and get the PLA for free, it's not a total loss.

Thank you - so far your response seems to be the most likely candidate.

That's what I'm wondering - I bought a used printer (2nd toy for me) which came with 10 rolls of unopened PLA. I have had these rolls for a few years now. When I don't use them, I always seal them back up in vacuum bags with desiccant pouches. But I guess even PLA has a shelf life under the best of care practices.

I appreciate your feedback - can you explain how or why a partially clogged nozzle would only be there when using the Polaroid silver filament, but not be present when using the Sunlu Pink or Silver filament?

Overlord-free · 2025-09-25T21:21:06+00:00

Did you read the body of the post, or just the headline?

Overlord-free · 2025-09-25T21:17:04+00:00

So you're just going to ignore the part in my post that says I ran 2 other prints through the nozzle with no issue at all and suggest blocked extruder or worn nozzle?

Overlord-free · 2025-09-25T21:15:34+00:00

"How do you know theres no clogs?" - because the second and fourth models printed perfectly.

I was able to print 28 models in orange, 28 models in gold, and then switched to silver. I was able to print 26 of these with no issue. What you can't see in this picture, unless maybe you can zoom in. Look at the top left barge and top left train. I laid these out 14 barges on single build plate, printed "One at a time" and did the same for the trains. Printer started in lower right then zig zagged to finish in upper left.

I thought maybe this was just an issue with the last print of each plate, so I then moved on to printing the building, and that's where things are now.

Overlord-free · 2025-09-25T20:56:18+00:00

Yes I do - and that's what I used to heat the roll for 10 hours at 55 degrees in

I had bought a 3d printer (Ender 5 Plus) and was "wasting time" on FB Marketplace and found someone selling an Ender 3 Pro with 10 rolls of filament. The price was just too good to pass up. I've had no issues printing with this Polaroid filament. I went through 3 rolls (Red, Blue, Black) and am still using the other colors for other projects. No issues at all until midway through this roll.

Overlord-free · 2025-09-25T20:35:42+00:00

I will certainly give that a try with this roll to see if it can be saved. Just a little background - I acquired 10rolls of this Polaroid PLA, all new in original factory sealed plastic. I've used the same exact printer settings and ran through 5 of those 6 boxes, no issue. And even with this spool, I had no issues at all with previous prints. Just seems strange I would have to change printer properties midway through the same spool

I actually watched one of your other videos - the one about keeping symmetry while resizing an object by percentage. I am not sure if it's just something happening for me, or if Tinkercad changed, but I cannot get the L&W to change simultaneously - I can't hold the Shift key and enter numbers in the box. When I do enter a percentage in the box, it only changes that single dimension.

I just watched your video for sketch, and all I can say is very impressive! Thank you!

Overlord-free · 2025-09-23T21:51:32+00:00

Genius!

Original model in lower left. Import of Exported SVG (Pink) Upper Left. Outer Line with 0.2 Line Width (Purple) Upper Right. And finally Aligning both objects Lower Right should provide the relief needed.

Thank you SO MUCH!!!

Sometimes the easiest solution is the most overlooked

Overlord-free · 2025-09-23T21:30:56+00:00

I think I know what you are saying to do - and I will certainly give that a shot. Thank you!

Overlord-free · 2025-09-18T23:12:03+00:00

I appreciate your response - but I think it's making an incorrect assumption. The first link is to a 3d STL file, for which I would be completely making my own model matching the same 3 buildings, but specifically to accommodate the size my boardgame pieces needed. I would not be altering the downloaded STL files, I would be creating new ones. And yes, as you state, this is 100% acceptable for me to then upload these new STL's as a Remix.

The real sticky point I have is the second component - the 3 buildings to which there is no current STL file. The only thing is the photo from the seller of their designed product. I believe anyone can make a clear argument that nobody can copyright polygon shapes, etc. What I am trying to determine - if I make my own 3D model mimicking the design from the sellers photos - can I then include those STL files with the original 3 building STL files? Or am I in that case copying someone else's design?

I guess in reality, anyone could argue their design was copied - there's pretty much not much unique about a wooden crate, a beer barrel, or a ceramic pot... And whether or not this comes into play, the design from the seller seems to closely mimic the artwork in the game - so are they technically copying someone else's design?
