1. General Description

Caricature chili-shaped keychain, with an expressive face sculpted in relief and a stylized flame at the top. The model is compact, solid, and designed to withstand daily use on a keyring. The attachment loop is integrated directly into the geometry.

2. Recommended Dimensions

(The model can be scaled without loss of functionality)

  • Total Height : 50 mm
  • Width : 18 mm
  • Thickness : 12 mm
  • Attachment ring : Ø 3.5 mm hole
  • Minimum wall thickness : 1.2 mm (3 perimeters)

3. Print Settings

Material

  • PLA : easy, clean, ideal for a decorative keychain
  • PETG : more resistant to shocks and abrasion
  • ABS : possible, but not necessary

Settings

  • Layer height : 0.12 to 0.20 mm
  • Nozzle : 0.4 mm
  • Infill : 15–25 % (Grid / Gyroid)
  • Walls : 3 perimeters
  • Bed : 55–65 °C (PLA), 70–80 °C (PETG)

Orientation

  • Printing lying on the back of the chili → Minimizes supports.
  • (Recommendation) Printing standing on the bottom of the chili → ensures a better face rendition

Supports

  • Yes, only :
    • under the flames
    • under the attachment loop
  • Density : 10–15 %
  • Angle : 50°

4. Post-processing

  • Support removal : easy, accessible areas
  • Light sanding : 400–800 grit to smooth the face
  • Painting (acrylic) :
    • Red : chili body
    • Yellow/orange : flames
    • White + black : teeth and eyes
  • Finish : matte or satin varnish to protect the colors

5. Tolerances & Robustness

  • General tolerance : ±0.2 mm
  • Reinforced attachment loop : minimum 3 mm thickness
  • Resistance : good in PLA, excellent in PETG

6. Modeling tips (if you want to modify the STL)

  • Keep slightly chamfered edges to avoid breakage.
  • Maintain a constant thickness around the loop.
  • Face details should be ≥ 0.4 mm deep to stand out well.
