# 3D-Triforce

A mathematical correct tetrahedron Triforce made with OpenSCAD for 3D-printing

![Printed 3D-Triforce Structure](/docs/triforce_printed.jpg "Printed 3D-Triforce Structure")

The used OpenSCAD version was  2015.03-2.

## Parameters

The script uses the following parameters add its beginning to modify the model.

Dimensions are in millimeter.

| Parameter     | Default |  Description                                         |

| --------------|---------| -----------------------------------------------------|

| edge_length   | 100.0   | The length of a tetrahedron edge.                    |

| frame_width   | 5.0     | The length for a frame edge                          |

| frame_standout| 5.0     | How much the edge is "extruded" out of the tri-force.|

The default parameters provide this model with a small frame to give it a 

3D-look:

Setting frame_standout to 0.0 gives a plain triforce where the frame only joins the 

tetrahedrons together:

Playing with frame_standout can create other interesting 3D-Models. Here is an example

with a huge frame_standout value of 36.0 mm:

## Printing Recommendations

Print with supports enabled. My recommended Cura slicer settings are

 * Support Placement: Everywhere

 * Support Overhang Angle: 50

 * Support Pattern: Concentric

 

Setting the "Outer Wall Line Count" to 5 creates more sturdiness and prevents

the infill from shining through.
