Halloween Cat Witch Keychain

Witch Cat Pumpkin Keychain: 4-Colour Multi-Material Print

A little black cat in a witch's hat, peeking out of a jack-o'-lantern. This flat, enamel-pin-style keychain prints all four colours on one smooth top surface, with a recessed white border around the outside for a clean, finished edge.

Features

• 4 colours: white, black, purple, and yellow or orange (pick your pumpkin colour)
• Flush multi-colour face, so the design is smooth to the touch
• Recessed white border frames the design
• Built-in key-ring loop with a 4.5 mm hole, fits standard split rings
• Includes a 3MF with all parts pre-aligned, plus separate STLs for each colour

Size: about 58 × 74 × 3.7 mm

Print settings

• Printer: multi-colour printer required (AMS, ACE or similar), since there are several colours per layer. Printed on an Anycubic Kobra X.
• Material: PLA, same material for all four colours
• Layer height: 0.2 mm, or 0.12 mm for crisper details
• Supports: none. Print flat, face up.
• Infill: 15%

How to load

1. Open the 3MF, or import all four STLs together and choose "Yes" to load them as one object with multiple parts.
2. Assign each part to a filament slot: white (base), black, purple and yellow/orange.
3. Slice and print. Colour changes only start above 2.5 mm, so the base prints quickly in one colour.

Tips

• If you see fine white strings on the edges, raise retraction slightly for your white filament, or clean them off with a quick pass of a heat gun.
• Check the eye shine and fangs in the slicer preview. They're the smallest details.
