Design every panel.
A browser-based 3D designer for footbags, juggling balls, and other sewn spherical objects. Paint each panel, save the design as a link, sew exactly what you previewed.
Every face is a panel.
Spin it, paint it, sew it.
Click to color.
Pick from 21 fabric colors, toggle suede texture on or off, and paint any panel by clicking it. Rotate and zoom the sphere from every angle in real time.
Any panel layout.
Ten built-in polyhedra from tetrahedron (4) to GP(4,0) (162). Or upload your own OBJ — every face becomes a paintable panel. No Goldberg math required.
Share a link, save a design.
Every design lives in a URL — share it with the stitchers in your group chat. Phase 2: export a laser-cuttable SVG with stitch holes already in place.
Three steps. One browser tab.
Pick a shape
Start from a soccer-ball truncated icosahedron, climb to a 162-panel Goldberg, or drop in your own OBJ. Every face becomes a panel.
Paint the panels
Click any panel in 3D to color it. Use the 21-fabric palette, paint all hexagons at once, or fill the unpainted ones with a chosen color.
Share or sew
Save the design as a URL or download it as JSON. Bring the link to your sewing machine, or (Phase 2) export the panels as a laser-cuttable SVG.
Ten built-in shapes.
Bring your own polyhedron.
Need something custom? Drop in any OBJ file and every face becomes a paintable panel — the same pipeline handles built-ins and uploads.
Anyone sewing a sphere.
Footbag stitchers
Design a 32-panel, 42-panel, or 92-panel bag in your team colors. Never redraw a cardboard template again.
Juggling-ball makers
Match a 5-ball set in consistent panel layouts and palettes. Pick custom weight, density, and panel count without buying from a catalog.
Hackerspace fab labs
Color a sphere, get a cut file (Phase 2). Run a custom hacky-sack workshop on the laser cutter you already own.
Sphere-curious crafters
Goldberg polyhedra you've seen on math sites — now with a fabric palette, a needle in mind, and a suede-texture toggle.
Free, MIT-licensed, self-hostable.
Paneler is built in public. Run it on paneler.app, pull the container into your own cluster, or fork the repo and bend it to whatever sphere you want to sew. Built on Next.js, three.js, and React Three Fiber.
