Model your Blender object in millimeters so you can export to your 3d printer

Make Sure it fits! The slicer that is!

It is important to remember that 3d printer slicers work in millimeters, specifically, the one we use here, the Chitubox slicer.

When you model in a 3d cad program, you need to make sure it is set up for the metric system.  Also, adjusting the size and dimensions of the measurement details, such as centimeters, millimeters etc.

Blender, the program we use for modeling on this site, does not come set up standard in the metric environment.  Check out the video below, and see how easy it is to change your Blender 3d settings to accommodate the use of millimeters for design work.

Important Notes for Modeling!

When you model in a 3d cad program, such as Blender or any other, if you cannot adjust your model size to fit within your 3d printer’s slicer, one of the best things to remember is factor the sizing within the slicer by 10s.

For example.  If your model is too large, adjust the percentage 10% at a time smaller, and vice-versa for small models.
