Operation Guide
There are two simple methods to add a hanging hole to a model: using parts and using negative parts.
1. Using Parts
After importing the model file, right-click on the model and select Add Torus Part.


Use the corresponding tools to adjust the part’s position, angle, and size to create a suitable hanging hole. You can also modify its color.

2. Using Negative Parts
Right-click on the model and select Add Negative Part, then choose a cylinder or torus as needed. (A negative part refers to a section that will be subtracted from the original model.)

Adjust the size and position of the negative part.

Click Slice, and you’ll notice that a through-hole will be formed at the location of the negative part.

Once confirmed, send the file to the printer and start printing.
Conclusion
One of the charms of 3D printing is its customizability. Whether it’s a free downloaded model or a purchased design, you can use this simple slicing trick to make it better suit your needs!
