Parametric

Slicing method

How the model becomes flat parts: parallel fins, stacked layers, a waffle, radial fins or fins along a curve.

Parallel fins: slices standing out of a backboard, side by side. The backboard can be one board, slats or none.
Stacked layers: slices glued on top of each other, lined up with dowels; they can be hollowed to save material.
Waffle: two crossing sets of ribs joined by half-lap slots.
Radial: fins round a central axis, held by slotted hub rings.
Along a curve: fins square to an oval or circle, shaped by formulas (or shape buttons) for their length, height, twist and outline.

Options

Spacing1 to 500 mm · step 0.5 mm: The distance between parallel fins, centre to centre.
Phase0 to 1 · step 0.05: Shifts every fin along by this fraction of the spacing, to move where the slices fall on the model.
Min fin0 to 200 mm · step 1 mm: Fins lower than this are left out, so you do not cut slivers.
Margin0 to 200 mm · step 1 mm: The border of backboard left round the fins.
Slat depth2 to 200 mm · step 1 mm: How deep each backboard slat is when the backboard is made of slats.
Tab depth0.5 to 50 mm · step 0.5 mm: How far each fin's tabs reach into the backboard.
Dowels1 to 12 · step 1: How many dowel holes line up the stacked layers.
Wall2 to 100 mm · step 1 mm: The wall left round a hollowed layer. Thinner walls save material but make weaker layers.
Spacing A3 to 500 mm · step 1 mm: The distance between the ribs of the first family (A).
Spacing B3 to 500 mm · step 1 mm: The distance between the ribs of the second family (B).
Fins2 to 360 · step 1: How many fins turn round the axis.
Hub radius1 to 1000 mm · step 1 mm: The radius of the hub the fins start from. A bigger hub leaves more room between fins at the centre.
From °-360 to 360 · step 5: Where the fan of fins starts, in degrees.
To °-360 to 720 · step 5: Where the fan of fins ends, in degrees. 0 to 360 is a full turn.
Hub width3 to 200 mm · step 1 mm: How wide the slotted hub rings are.
Guide W10 to 2000 mm · step 5 mm: The width of the guide oval (or the diameter of a circle) the fins stand square to.
Guide H10 to 2000 mm · step 5 mm: The height of the guide oval.
Fins3 to 600 · step 1: How many fins stand round the curve.
Spacing1 to 200 mm · step 0.5 mm: The distance between fins measured along the guide curve.
Outline W10 to 3000 mm · step 5 mm: The width of the oval outline that trims the fins.
Outline H10 to 3000 mm · step 5 mm: The height of the oval outline that trims the fins.
Plate border0 to 200 mm · step 1 mm: The border of back plate left round the fins.
Faces4 to 1000 · step 10: How many flat faces the folded model has. Fewer faces are quicker to fold; more follow the model more closely.
Tab height2 to 30 mm · step 0.5 mm: The height of each glue tab; tabs on short edges are made smaller.
