Lotus Diya Tealight Set with Platter (Parametric, LED-Safe Diwali Decor)

LED TEALIGHTS ONLY. These are printed plastic cups. Never use a real flame, burning candle, hot wax, oil, incense or a hot metal insert in them. This is a decorative LED holder for Diwali, not a fire-safe diya. Untested prototype: no physical print or heat test has been done yet.

CUSTOMIZABLE (this is the point of the model)

This is a parametric lamp template, not a fixed shape. The cup count (1, 3, 5 or 7), cup diameter, platter diameter and petal count are all parameters, and the full native TrueGeometry Playground command recipe is below. Change the numbers, rebuild, and you get your own set. The default build is 5 removable cups on a 190 mm lotus-edge platter.

DEFAULT DESIGN

- 5 separate removable cups on a 190 mm x 3.2 mm lotus-edge platter, 16 lobes

- Cup clear diameter 41 mm, height 16 mm

- Cup bottom outer diameter 45.8 mm, rim outer diameter 52.8 mm

- Wall minimum 2.4 mm, floor 2.4 mm with an intentional 2 mm center vent

- Cup centers on a 55 mm radius ring

- Cup revolve is 32-sided (native Playground tessellation limit)

- Native Playground meshes, not repaired. No slicer or physical print test, so no watertight claim is made.

FILES

- Full assembly (first file): Full default assembly snapshot: five LED tealight cups on the platter. Native Playground geometry, original Y-up coordinates, with no repair or union. Six separate closed shells in the STL; not a print-in-place assembly. No slicer or physical print test. Use the separate cup and platter files for printing. LED tealights only.

• LotusCup.stl: print one per tealight (5 by default)

- LotusPlatter.stl: flat lotus-edge platter

- Guide PDF: how to run a command script in TrueGeometry Playground

- Gallery: 3 renders (iso, top, front) and the 2 guide pages

HOW TO CUSTOMIZE

Cup count: for N cups, cup k (k = 0 to N-1) goes at x = R*cos(360*k/N degrees), z = R*sin(360*k/N degrees). R is 55 mm by default. For 7 default-size cups use R = 66 mm and a 220 mm platter. Editing a set_var line alone does not rebuild the platter outline or the cup placements, so regenerate those after changing dimensions.

Cup diameter: the cup is a revolved profile, inner radius = clear diameter / 2 (20.5 mm for 41 mm). Measure your LED tealight and print one cup first as a fit test.

Petal count: the platter edge is a closed point list passed to sm_part with sm_params 3.2 1 0.44 (3.2 mm thick). Rebuild the outline with a different lobe count for a different edge.

To run the recipe: open TrueGeometry Playground, start an empty scene, open Script, paste the recipe, run. The guide PDF shows the steps. Playground: https://www.truegeometry.com/CoreWebGLTG/KBEAgentHTTP.html

PRINT SETTINGS (starting points, not a tested profile)

- 0.4 mm nozzle, 0.2 mm layers, at least 4 walls, at least 4 top and bottom layers, 15-20% infill

- No supports needed on the nominal design: the cup wall flares only 3.5 mm over 16 mm height (about 12.3 degrees from vertical)

- Print each cup floor-down and the platter flat. The 190 mm platter needs a bed of about 200 mm or more.

- The STLs use Playground Y-up coordinates. In your slicer rotate +90 degrees around X, then place the part on the bed.

- Print one cup first and check it against your LED tealight.

LIMITS

- Not fire safe, LED tealights only

- Untested: no physical print or thermal test done

- Cups are loose, not attached or captive. The platter is for display, not a carry tray.

- Lotus detail is on the platter edge, not on the cup rims

- Created with AI assistance in TrueGeometry Playground
