Banana for Scale

A FreeCAD addon that puts a banana, a soda can or a 3DBenchy next to your model, so you can see at a glance how big it really is.

FreeCAD with the Banana for Scale toolbar button and its tooltip, a yellow 3D banana and a red soda can in the viewport.

Three things to measure against

  • BananaAbout 180 mm long, so a quick sense of scale in any model.
  • Soda canA classic 440 ml can for the more practical reference.
  • 3DBenchyThe famous boat, for when the model is a print test.

How to use it

  1. Open the Addon Manager from the Tools menu and search for Banana.
  2. Install it and restart FreeCAD. The toolbar buttons only register at startup.
  3. Pick an object from the Add Object for Scale dropdown. The transform tool opens right away so you can move it into place.
