How to Modify STL Files for Custom 3D Prints: A Step-by-Step Guide

3D printing provides endless possibilities for personalization and customization. In this blog post, we will guide you on how to modify STL files for your own custom prints using and Tinkercad, an easy-to-use, online 3D modeling platform. Whether you already have an STL file or you've found one online, we'll show you how to add your own branding or modifications to it.

Step 1: Finding and Downloading Your STL File

Firstly, you need to have an STL file to work with. This could be a file you've created, or it could be a file downloaded from an online platform like Thingiverse. For this guide, we'll use the example of a penguin utility case downloaded from Thingiverse. After finding the desired item, simply click "Download" to download the STL file.

Step 2: Accessing Tinkercad

Once you've downloaded your STL file, navigate to Tinkercad, a free online tool that allows users to create or modify 3D designs. To begin, click on "Create," and then select "3D design."

Step 3: Importing Your STL File into Tinkercad

Next, you'll want to import your STL file into Tinkercad. To do this, click on "Import," then choose the STL file from your device and ensure the measurement units are set to "millimeters." Once you've imported the file, it will appear within the editor. In this case, we're working with the lid of our penguin utility case.

Step 4: Importing and Adjusting Your Logo

Now, it's time to add your logo. Your logo should ideally be in SVG format for best results. Once you've located your logo, drag it into the Tinkercad editor. You'll likely need to adjust the size of your logo to fit properly onto your item - you can do this by dragging the corners of the logo within the editor. In this case, we want the logo to be indented onto the lid.

To achieve this, change the logo's property to "Hole" using the dropdown menu at the top of the Tinkercad interface. Then, align the logo to your desired location on the item.

Step 5: Exporting Your Modified STL File

Once your logo is perfectly aligned, it's time to export your newly modified STL file. Simply click "Export," and make sure to select ".STL" as the format. Tinkercad will then prepare the model for export, and once it's done, you can download the file.

Step 6: Uploading Your Custom Print to

Finally, navigate back to and select "Custom Print." Drag and drop your newly modified STL file into the designated area, name your project (e.g., "case lid with logo"), and then click "Add to Cart." Intagly will automatically slice the model, calculate the printing time, and provide an instant quote. You can then proceed to checkout and wait for your custom print to be shipped to your door.
