Remove Small Parts tool settings panel
Remove Small Parts filters out disconnected pieces that are too small to print. Models often contain tiny floating fragments from modeling or import errors.

​
When to use this

  • Your model has small floating pieces or stray geometry
  • After importing a complex scene with debris
  • When the Errors tool shows many disconnected components

​
Settings

​
Min Size

The Min Size (% of Largest) slider removes parts smaller than this percentage of the largest part. Range 0.1–20 percent. Default: 1 percent.

​
Min Face Count

Remove parts with fewer faces than this count. Set to 0 to disable.

​
Step by step

1

Select Remove Small Parts

Click the tool in the Interactive Tools section.
2

Adjust the threshold

Set the minimum size percentage. Start with 1% and increase if needed.
3

Apply

Click Apply. Small fragments are removed.

​
Tips

  • Start with 1% and increase gradually — you don’t want to accidentally remove important parts
  • Use the Errors tool first to see how many disconnected parts exist
  • This won’t remove parts physically connected to the main model — only truly separate floating pieces
