Unequal open compartments and a broad pouring corner keep the task visual, with no need for a complicated mesh sieve.","category":"Plant care","difficulty":"Beginner","measurements":["Smallest and largest pebbles in the decorative set.","Number of groups to keep separate.","Available sorting area on the work surface.","Opening width of the storage containers used afterward."],"prompt":"Model a decorative pebble sorting tray with tray_width, tray_depth, compartment_widths, wall_height, pour_corner_width and inside_radius. Ask for missing sizes and the number of groups. Use broad accessible compartments with low rounded dividers. Add one open pouring corner per section where practical. Do not include a calibrated sieve, drainage system or food-contact claim.","steps":[{"title":"Arrange representative groups","detail":"Sort a few pebbles on paper first. Give larger pieces more compartment width rather than dividing the tray into identical cells by default."},{"title":"Build the compartment layout","detail":"Create one continuous base and add low dividers. Round each internal corner so small stones cannot disappear into narrow inaccessible pockets."},{"title":"Review emptying paths","detail":"Shape a broad corner exit for each compartment. Check that tilting one section toward its exit does not require pouring across another group."}],"checks":["Compare the largest pebble with every compartment opening.","Review the pouring geometry against the storage-container opening.","Inspect the exported tray for a continuous floor beneath all dividers."],"pitfall":"A decorative funnel narrower than the largest stone can jam even when the compartment itself has ample space.","scope":"A proposed dry sorting accessory for decorative material, not a horticultural filter or calibrated grading tool.","materialNotes":"PLA suits dry layout exploration. PETG is another candidate for occasional damp material; abrasion and cleaning behavior remain untested.","links":{"html":"https://partsforagents.com/vibe-cad/decorative-pebble-sorting-tray","markdown":"https://partsforagents.com/vibe-cad/decorative-pebble-sorting-tray/guide.md","json":"https://partsforagents.com/vibe-cad/decorative-pebble-sorting-tray/guide.json","catalog":"https://partsforagents.com/vibe-cad/catalog.json","order":"https://partsforagents.com/for-humans?project=decorative-pebble-sorting-tray#workspace","agent_handoff":"https://partsforagents.com/guides/cad-to-print#connect","full_mcp":"https://partsforagents.com/api/mcp","free_advice_mcp":"https://partsforagents.com/api/advice/mcp","tool_schemas":"https://partsforagents.com/tools.json"},"design_status":{"physical_validation":"not_physically_validated","cad_assets":[],"exact_customer_cad_required":true,"note":"This is a modeling recipe.
