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...

Don't look at the patterns. These are warts. I'm betting the other question I posted as a duplicate might answer your question.

@Pᴀᴜʟsᴛᴇʀ2: I don't actually see any answer about the bumps/warts on the linked question.

# Weird deformities on surfaces with ender 3

(Asked by: username_0 on 2020-02-20)

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.
