• Triangle congruency

Customization

Sizes

• Small - 60mm of travel
• Large - 120mm of travel

Track Styles

• Standard - Supports infinite angle and distance settings
• Click - Supports a smaller range of settings for the benefit of locking into predefined positions

Dial Styles

• Large - Better grip
• Small - Less obtrusive

Optional

Print a mini wrench to make tightening dials easier.
WARNING: Do not over-tighten.

Printing

• Designed for 0.2mm layer heights
• All parts can be printed without supports
• How well sliding parts move will depend on print quality
• Avoid brittle filaments to prevent parts from snapping
• Swap filaments mid-print for easier to read dials
   

Parts List

To print a triangle, you will need three copies of both the top and bottom track of the size and style of your choice. You can mix track lengths but you cannot mix track styles.

You will also need 6 dials, which can consist of a mix of small and large sizes.

Assembly

See video above for a step-by-step assembly.
