+=== Cura is slow ===
+If Cura is slow: set the option "Infill > Skin Edge Support layers" to 0
+{{:prepare_for_3d_printing:slow_cura_trick.png?600|}}
+=== Per model settings ===
+{{:slicers:per_model_settings_-_result.png?600|}}\\
+Use different slicer settings in the volume of a selected object.
+**Example**: use a more dense infill in a specified area
+  * Add the object you want to print.
+  * Add the object you want to define the dense infill with (a cube could work just fine).
+  * Change the size and position of the second object so it overlaps the first object at the desired location.
+  * Select the second object. In the side bar, go to ''per model settings'' and select ''Modify settings for overlaps''.
+  * select ''infill mesh only''
+  * select the following settings:
+    * Wall line count: ''0''
+    * Top Layers: ''0''
+    * Bottom Layers: ''0''
+    * Infill Density: the desired value for your print
+{{:slicers:per_model_settings_-_settings.png?600|}}\\
+When you're using Gradual Infill Steps in your main model, don't forget to add ''Gradual Infill Steps: 0'' to the per model settings
+=== Calibrating for correct dimensions ===
+  * Isolate a small piece of your model which you can use for a fit-test.
+  * In Cura, set the ''Horizontal offset'' to a negative number (in mm) to make the model leaner in the horizontal plane. Set it to a positive number to make it fatter. Use small values like for example ''0.1mm''.
+  * Print the test piece and measure it with calipers.
+    * If the dimensions are different than the CAD model, adjust the horizontal offset.
+    * If the dimensions are the same as the CAD model, but it doesn't fit properly, adjust the clearance values in the CAD model.
