Conversation Heart Bag/Purse

Conversation Heart Purse / Bag (Mom & Me Scale-Friendly)

This conversation heart purse is a playful, wearable accessory inspired by classic Valentine candy hearts. The design balances cute aesthetics with real-world printability, making it accessible for home makers while still producing a functional, eye-catching result.

The purse features an open-top design with no closure, giving it a clean silhouette and a lightweight, grab-and-go feel. It works well as a costume accessory, themed bag, photo prop, or fun statement piece for Valentine’s Day and beyond.

Design Rationale (Why This Is a Multi-Part Print)

Although this bag could technically be printed as a single piece, doing so would require significant internal and external supports due to the open top, curved interior walls, and heart-shaped overhangs. Those supports would increase print time, waste filament, and be extremely difficult to remove cleanly from inside the bag—often damaging surface finish.

To avoid this, the model was intentionally designed as a multi-part print, improving efficiency, reliability, and final quality.

Design & Assembly

The bag consists of:

• A base section
• A top section (with either a decorative “LOVE” heart or a blank heart option)
• A printed chain/strap (optional and scale-matched)-use as many as you see fit

The top includes integrated alignment pins that snap into the base to form the complete bag. This snap-fit design allows each piece to print flat on the build plate, typically without supports.

Because printer tolerances vary, a small amount of super glue may be added during assembly for extra durability—especially for larger prints or frequent use.

Printability & Accessibility

This approach:

• Eliminates heavy support requirements
• Reduces filament waste and print time
• Improves surface finish
• Increases success rates across different printers

Each component prints cleanly and reliably, making the model beginner-friendly while still offering flexibility for experienced makers.

Recommended Print Settings (FDM/FFF)

• Material: PLA (easy) or PETG (more durable)
• Layer height: 0.20 mm (0.28 mm acceptable for faster prints)
• Walls/Perimeters: 3 recommended
• Top/Bottom layers: 4–5
• Infill: 10–20% (increase if more rigidity is desired)
• Supports: Not required in most cases
• Adhesion: Brim optional if needed
• Orientation: Print flat on the build plate as provided.

Customization & Finishing

The “LOVE” heart top is designed to be a two-color feature. In the example shown, the base heart was printed in pink and the lettering was painted with the color painting option in the slicer to mimic the look of traditional conversation heart candies and provide clear contrast.

This detail is optional and can be achieved in multiple ways, including:

• Hand painting after printing
• Color changes at layer height
• Filament swaps
• Multi-material printers

The blank heart top is included for users who prefer a solid-color look or want to add their own custom text or designs.

Scaling Guide (Mom & Me Friendly)

This design scales cleanly without modification:

• 100% scale → mini / child-size bag
• 150–200% scale → adult-size bag

This makes it ideal for matching Mom & Me sets. When scaling up, increasing wall count can help maintain stiffness and durability.

Use Notes

Because the bag has an open top and no closure, it is best suited for lightweight essentials such as a phone, lip balm, keys, or a small wallet. For heavier use, PETG and/or adhesive reinforcement is recommended.

TL;DR (Design Summary)

This model is intentionally designed as a multi-part, snap-fit print to avoid excessive supports, reduce filament waste, and improve surface quality. Splitting the design allows each piece to print flat and support-free, resulting in a more reliable, scalable, and user-friendly build while maintaining both function and aesthetics.
