This is a 3D-printed cookie jar modeled after the head of Jack Skellington from The Nightmare Before Christmas. The main part of the jar is his skull-like head, which has been hand-painted with black details for his eye sockets, nostrils, and stitched mouth. The top of the head is open to hold cookies or other treats, and the lid, which is also 3D-printed, fits snugly on top to complete the iconic design.

Here is a technical sheet and printing details for the Jack Skellington cookie jar.

Jack Skellington Cookie Jar - 3D Print Technical Sheet

Figure Description

This model is a hollow, two-part replica of Jack Skellington's head from The Nightmare Before Christmas, designed to function as a cookie jar. The design is optimized for FDM (Fused Deposition Modeling) 3D printing and features a separate lid that fits securely on the main head portion.

Technical Specifications

• Dimensions (As Printed):
  • Main Jar: Approximately 160 mm (height) x 180 mm (width) x 170 mm (depth)
  • Lid: Approximately 25 mm (height) x 155 mm (diameter)
• Total Weight: Varies by infill density and material, typically 250-400g for PLA.
• Parts: 2 (Main Jar and Lid)
• Assembly: None required. The lid is a pressure-fit design.

3D Printing Details & Recommendations

Filament

• Type: PLA (Polylactic Acid) is highly recommended for its ease of use, stability, and non-toxic properties, making it safe for indirect food contact.
• Color: White or a similar light color is ideal as a base for hand-painting the details.

Printer Settings

• Layer Height: 0.20 mm is a good balance between detail and print time. For smoother finishes, consider 0.16 mm.
• Infill: 10-15% is sufficient for structural integrity while keeping the model lightweight and reducing material usage. Use a standard pattern like grid or cubic.
• Supports: The model is designed to be printed with minimal support.
  • Main Jar: Requires supports for the underside of the chin and eye sockets.
  • Lid: No supports are typically needed.
• Raft/Brim: A brim is highly recommended for both parts to ensure good bed adhesion and prevent warping, especially for the large, flat bottom of the main jar.
• Nozzle Temperature: Follow the filament manufacturer's recommendations, typically around 200-210°C for PLA.
• Bed Temperature: 60°C is standard for PLA on most heated beds.
• Orientation: Print both the main jar and the lid upright.

Post-Processing

• Support Removal: Carefully remove all support material from the jar, particularly from the chin and eye areas.
• Sanding: Light sanding can be done to smooth out layer lines, if desired.
• Finishing: The model is perfect for hand-painting. Use acrylic paints for the black details of the eyes, nose, and stitched mouth. A clear coat of varnish can be applied to protect the paint and give it a slight sheen.
