3D printed octopus is always popular with people who like 3D printers. It’s cute and useful, so it’s no surprise that we all love it. If you have a 3D printer nearby, why not try to print some models of octopuses? In this article, we will guide how to 3d print an octopus step by step and there are also 7 popular and best 3D printed octopus stl files that can be downloaded.

For example, you can 3D print an octopus with legs that move around. You could also use an octopus model to try out different filaments, especially ones that are flexible. 

Also, if you like plants, there are even planters that look like octopuses. Let’s take a look at some of the best octopus models that can be printed in 3D.

How to Make a 3D Printed Octopus?

  1. Choose the octopus models you want to print and click on Thingiverse files.
  2. Let’s go to Thingiverse details and look at the developer’s suggestions so that we can remember them when we’re messing with the slicer.
  3. Go back to Thingiverse files and click the download button for either the octopus support or the spiral sub, depending on what you chose to print.
  4. Once that’s done, click on this carrot-showing folder, hold down on the STL file, and drag it to the Cura software. Once you plug it in, it should take a few seconds to load up, and when it does, you’ll see a cute little model right on your screen.
  5. Let’s start playing around with the settings now. First, we’ll go to the profile tab, click on this box, and choose a layer height of 0.2 millimeters. Click on that, and if this window pops up, click “Discard Changes.” We don’t want to use any of the old print settings from your last print job, so we’ll use completely new settings here.
  6. The next setting we’ll change is infill. If you like weights on your model as I do, set this info density to 15 and forget about the zero percent for tentacles infill and the 15 for everything else like the head. I like when the legs shake because of the weight, so if you’re a beginner, stick with 15.
  7. Save the file, and then send it to your printer.
