Soap Dish
A figure-8 (bilobate) soap dish with a rectilinear infill base and a non-planar spiral wall. The two lobes share a narrow waist, and the outer corners sit higher than the waist to let water drain toward the center. The toolpath alternates infill angles (45° / 135°) on the base layers, then spirals upward with a height profile that rises and falls around the perimeter.
See Predefined Models for the general workflow and how to select this model.
Parameters (sliders)
Parameters
Length- Total dish length (L1) in mm. Sets how elongated the figure-8 is along its long axis.
Width- Total lobe width (W2) in mm. Width of each lobe at its widest point.
Waist Width- Width at the narrow waist (W1) where the two lobes meet. Smaller = more pinched figure-8.
Outer Height- Wall height at the outer lobe corners. The highest point of the non-planar wall.
Inner Height- Wall height at the waist concavities — set this lower than Outer Height so water drains toward the waist.
Material Thickness- Layer height / extrusion height (EH) in mm. Set equal to your nozzle diameter for stable adhesion.
Width/Height Ratio- Extrusion width to height ratio (EW/EH). Controls line width relative to layer height.
Overlap- Lateral overlap between infill lines (0–40%). Higher overlap gives a denser, water-tight base.
Base Layers- Number of rectilinear base layers, alternating 45° / 135° crosshatch before the wall begins.
Quantity- Number of dishes generated side by side in one job.
How it works
- The figure-8 outline is built from two circles of Width/2 radius, joined by tangent lines that narrow to Waist Width.
- Base Layers are crosshatched: odd layers at 45°, even layers at 135°, giving a solid bottom for water resistance.
- The wall then spirals upward with a cosine height profile — Outer Height at the two lobe tips, Inner Height at the waist on either side.
- A single continuous toolpath means no seams on the wall.
