Today I noticed some weird holes/deformities on the surface of this simple usb holder I printed. Since I'm fairly new to 3d printing I have no idea what may be the cause of this problem

My printer is a Ender 3 (Marlin 2.0.3) and I'm using Cura for slicing.

It would be a great help if someone could give me some pointers on how to fix this.

  • $\begingroup$ Well, as I mentioned I'm new to 3D printing and searching is a bit difficult when I don't even know what the problem is called. I have seem plenty of posts on "blobs and zits", "under extrusion" and whatnots yet I couldn't find a similar distortion pattern. It would be really nice if anyone could tell me what I'm supposed to look for, give me a link to check or anything else... $\endgroup$

  • $\begingroup$ Don't look at the patterns. These are warts. I'm betting the other question I posted as a duplicate might answer your question. $\endgroup$ Feb 20 '20 at 3:48
