Thermoform Hearts

Thermoform kit for hollow heart ornaments with messages

Thermoform Hearts

Ready-to-print thermoform kit for hollow heart ornaments with a message on the front: heat a thin plastic sheet, press it between the female and male molds, and it forms a glossy heart-shaped shell. Each shell closes onto a printed base plate that carries the message lettering, and the two halves join with the screw cap + clip into one hollow hanging ornament — the cap doubles as the hanger for a ribbon or cord. No customization needed: slice, print and form.

Ready-Made Messages

English: I love you · Happy Birthday · Congratulations · Happy Easter · Merry Christmas · Happy Mother’s Day · Happy Father’s Day · Be my Valentine · Thank you · Get well soon

Português: Te amo · Feliz Aniversário · Parabéns · Feliz Páscoa · Feliz Natal · Feliz Dia das Mães · Feliz Dia dos Pais · Feliz Dia dos Namorados · Obrigado · Fique bem logo

Español: Te amo · Feliz Cumpleaños · Felicidades · Feliz Pascua · Feliz Navidad · Feliz Día de la Madre · Feliz Día del Padre · Feliz Día de San Valentín · Gracias · Que te mejores

Key Features

30 ready-made messages plus a blank pair: 10 phrases in each of English, Portuguese and Spanish, plus Heart-Empty base plates with no lettering at all — for an unlettered heart or your own finish

Print the molds once, reuse for every message: the mold pair and the connectors are shared across all messages and sit once at the top of the ZIP

Size: each heart measures about 14 × 13 cm (the printed base plate is 142.7 × 131 mm) and the assembled ornament is roughly 5 cm deep (each formed half is 2.5 cm)

Material split: the molds are preferably printed in PETG so they don't stick to the PLA base when it gets hot during forming (PLA fuses to PLA; PETG doesn't); the base plates, cap and clip print in regular PLA

Customizable version available: this printable is the ready-made counterpart of the Thermoform Generator model

Files

Shared, at the top of the ZIP (print once, reuse for every message): Heart-Molds (the mold pair, identical for all messages), Heart-Connectors (screw cap + clip), Heart-Empty (a blank pair of base plates, no message at all)

One folder per message under , and : \<Message\>-Full (both plates in one print), \<Message\>-Left / \<Message\>-Right (one half each)
