BREPcode v0.5.0: FizzCore + printable support fins

FizzCore bubble infill and printable support fins

Drop an STL / 3MF / OBJ anywhere on the page and BREPcode now asks what you came to do: open it, fill it with FizzCore bubbles, add support fins, or open it and jump straight to a tool.

FizzCore bubble infill

• Fills a part with graded bubbles: big in the core, small and dense under the skin, small ones packed into the gaps.
• Every bubble gets a 45° teardrop top, so no ceiling inside needs support.
• Pick your nozzle and it sizes the skin, the webs and the smallest bubble in whole extrusion lines.
• Solid webs (the bubbles are the infill) or Hybrid (wide webs that get your slicer's gyroid).
• Shows plastic saved and an "equivalent slicer infill %" so you can compare it honestly with gyroid.

Support fins

• Tilts the part (45° by default) with a live low-poly preview before the full run.
• Fins are grown up from the bed a 0.2 mm layer at a time with every layer within 45° of the one below, so nothing floats and nothing overhangs.
• The contact edge is a straight line laid against the part's bulges, and tiny pokes stop 0.2 mm short so they catch a teetering part but never fuse.
• Fins stop a little past the part's centre of mass by default. They prevent tipping; a face that already prints doesn't get a tall fin.
• Auto picks the lean direction (least overhang) and the fin side (where it would tip).
• Overhangs on the part itself are painted red, and a button finds the tilt with the least overhang.
• Spin, flip, or click a face to lay it flat: the fins stay put and re-fit.
• Basics in the panel; fin size, thickness, spacing, distance from model, poke gap and foot size under Advanced.

Notes

• The Claude Code agent bridge is off in this download. Start BREPcode.exe --agent to let Claude Code drive the app (see docs/AGENT.md).
• Windows portable exe: no installer, just run it.
