"LYSHJERTE" Giant Modular Heart for Outdoor Decor

A huge, modular heart frame for making large-scale Christmas or winter decorations. 

The assembled heart is about 1 meter (3 feet) wide, designed to be seen from a distance – perfect for the garden, driveway, or front of the house.

This is a simple, robust base for big seasonal statements – easy to print, quick to assemble, and fun to decorate.

Design & parts

• Modular build in 10 pieces
• Printed from 3 plates
• Parts are approx. 10 mm thick (slightly less than ½ inch)
• Dovetail joints for easy alignment and a sturdy shape
• No supports needed on most printers (flat parts), although a brim is added to avoid the parts moving around

Assembly

1. Print all parts.
2. Remove the brim – either by using your fingers or a small set of pliers
3. Slide dovetail joints together to form the full heart. 
   1. Left side is mirror of right
   2. See the drawing and note the difference between dovetail orientation, left and right side. 
   3. All parts must face same face up as printed. Easiest to ensure with e.g. a texture plate
4. Secure every joint with strong tape (canvas/gaffa/duct tape).
   • The dovetails align the pieces; the tape provides long-term strength, especially outdoors.

Material recommendation

Print in PETG or another weather-resistant material. PLA will work for indoor use, but can deform or become brittle outside.

Decorating ideas

• Wrap a string of lights around the frame
• Add fir branches/greenery, ribbon, cones, or ornaments
• Mix lights + greenery for a classic festive look

Mounting the Heart

Mount with a weather resistent string or similar. Enjoy!
