Ultimate Resin Letter Keychain Generator V2

Membership

V2 Update - Added no icon option

Create professional-looking, chunky bubble-style keychains right at home!

This parametric generator is designed specifically for makers who love combining 3D printing with epoxy resin crafts. The letters feature raised walls that form a perfect "bath" or cavity intended to hold resin, allowing you to create a stunning, glossy, glass-like finish.

Key Features:

• ✨ Resin-Ready Design: Deep recessed letters designed to hold epoxy resin cleanly. The walls allow you to overfill slightly, using surface tension to create a beautiful "domed" effect.
• 🎨 Fully Customizable: Choose any initial (A-Z) and pair it with a cute decoration icon (Flower, Heart, Star, Crown, Diamond and no icon at all).
• 🌈 Multicolor Friendly: The model is segmented and pre-colored for easy multi-color printing (perfect for AMS users).
• 👌 Easy to Print: Designed to print flat on the build plate with absolutely no supports needed.

PRINT INSTRUCTIONS:

The provided profile is set up for a balance of strength and print speed using standard settings.

Recommended Settings:

• Nozzle Size: 0.4mm standard
• Walls / Perimeters: 2 (Sufficient for structural integrity for this model)
• Infill Density: 15% (Gyroid or Grid pattern recommended)
• Layer Height: 0.2mm (A good balance for quality results)
• Supports: None required.
• Material: PLA works perfectly.

AMS/Multicolor Note: ensure your filament colors are assigned correctly in the slicer before printing to get the multi-colored base, letter, and icon effect.

POST-PROCESSING GUIDE (Resin Filling):

While the print looks great on its own, follow these steps for the glossy "bubble" effect:

1. Ensure your 3D print is clean and free of stringing.
2. Mix a small batch of clear 2-part epoxy resin.
3. Using a fine syringe, pipette, or toothpick, slowly fill the white cavity inside the letter.
4. Pro Tip: Fill it just until the resin reaches the top edge of the white wall. Surface tension will keep it from spilling over, creating a nice rounded dome.
5. Place the keychain on a perfectly level surface and allow the resin to cure completely according to the manufacturer's instructions (usually 24 hours).
