====== Prepare for 3D printing ======

===== Prepare your 3D mesh =====

  * watertight
  * not too many intersections
  * avoid small details (0.8mm minimum detail, but tall objects should be thinker)
  * if part snaps together with other part: allow clearance
  * if part snaps together with other part: make sure the part can be inserted


===== Slicing tips =====
==== Cura ====

=== Cura is slow ===
If Cura is slow: set the option "Infill > Skin Edge Support layers" to 0

=== 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

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.
