About this project
A trivet woven from overlapping wavy rings. The rings cross each other in a rosette, giving an open, flat mat for a hot pot or teapot that prints in one piece, with a loop at the top so it can hang on a wall hook when not in use.
How it's built
- Ring - an equation curve, a circle whose radius ripples with a sine wave, drawn as a band of constant width.
- Rings - a radial repeat copies that one ring evenly around the centre; every crossing is blended with a fillet.
- Loop - a ring on top of the upward-pointing ring, placed by formula so its hole always clears the band, whatever the size, wave or ring count.
- Body - the 2D pattern is inflated into a slab with rounded edges.
Parameters
| Group | Slider | What it does |
|---|---|---|
| Rings | Ring radius | Size of each ring |
| Rings | Rings | 2-6 overlapping rings |
| Rings | Offset | How far each ring sits from the centre; larger = wider, more open |
| Wave | Amplitude, waves | Height and count of the ripples; 0 amplitude gives plain circles |
| Band | Width, blend, thickness | Band width, crossing fillet and slab thickness |
| Hanging loop | On/off, loop radius, hole radius | Size the hole for your hook or nail |
Sliders guard themselves: the rings always overlap enough to stay one piece, and the ripples can't get so steep they fold over. Many fine waves make a very detailed mesh, so expect slower updates at the top of the wave-count range.
Printing
Print flat on the bed. For hot pots, PETG or ASA hold up far better than PLA.
