Rangoli stencil 150-330 mm, keyed pieces for 180 mm beds

Lets you lay down a rangoli pattern of petals, crescents and dots in coloured powder without drawing it freehand. It comes as four keyed pieces, so a design wider than your print bed still goes together. Change the diameter and the petal count to suit your doorstep.

Parts

  • stencil-sector ×4 · PETG · Flat, as modelled (top-rounded face up, flat face on the plate)

    At the defaults: four identical quarters, each 157.4 x 149.9 x 1 mm including tab and knobs, about 18 g and 27 min. Rim and hub jigsaw knobs lock each piece to the next. Each piece has a hang/lift tab with a 4.4 mm hole. The petal slider is even only, and the piece count follows it (all checked at 3

Print settings

Layer height
0.2 mm (a 1.0 mm sheet is 5 layers)
Walls
2 (the engine's default; the sheet prints almost entirely as solid layers)
Infill
15% (the engine's default; it has almost no effect on a 1 mm sheet)
Supports
None. The part is flat, with 0% overhang.
Notes
Default figures from the build report: about 18 g and 27 min per quarter, 73 g and 1 h 49 min for all four, in PETG. Every piece is entirely first layers, so clean and level the plate and print the first layer slowly.

Assembly

  1. Print the stencil-sector part as many times as the Print tab shows: 4 at the defaults, or 4-7 depending on the petal count.
  2. Lay the pieces on a clean, flat floor and press each piece's rim knob and hub knob straight down into the neighbouring piece's sockets.
  3. Fill the cut-outs with rangoli powder, tapping it level with the top of the sheet.
  4. Lift the stencil straight up by the tabs, one piece at a time if the joints feel loose, so the powder lines stay crisp.
  5. Tap off the powder and store the pieces flat or hung by the tab holes.

Good to know

  • Checked in the Loftsmith engine only; not printed. The jigsaw keys are modelled with 0.15 mm clearance per side. If they are tight on your printer, sand the knobs lightly. If loose, use a strip of tape on the underside.
  • The keys hold the pieces together only on a flat floor. Lift and carry the stencil piece by piece, not as one sheet.
  • The petal count must be even (6-16) so every seam falls on a web between petals.
  • The pattern comes from a fixed set of motifs (outlined petals, drops with dots, leaf lattice, crescents, bead rings), so you cannot draw your own design.
  • With 4 rings, and at small diameters, the inner petals become plain cut-outs instead of outlined petals, because the ring is too narrow to hold an island.
  • At the smallest bridge width (1.6 mm) the bridges are about 4 extrusion lines wide and can tear if the sheet is folded sharply. Use 2.4 mm or more for heavy use.
  • Fine powder can creep under a 1 mm sheet on uneven floors.
  • The largest stencil is 330 mm. Bigger floor rangoli need several stencils.
