4-Part Click Frame Generator (Parametric)

This parametric model generates a large picture frame split into 4 printable parts, designed to fit standard build plates while still allowing you to create larger frames.

Each part consists of:

• a backplate
• a frame wall (side)
• a front picture overlap (lip)

The four parts connect using integrated connectors and form a rigid square frame when assembled.

🧩 Key Features

• 4-part modular frame design (easy to print, large final size)
• Integrated click-fit (snap-fit) connectors
• Built-in screw holes on the back for wall mounting
• Works as a standard frame or shallow shadow box
• Fully parametric and customizable

⚙️ Parameters (Parametric Model Maker)

You can adjust:

• Picture width & height
• Frame border width and height
• Backplate thickness
• Picture overlap (front lip)
• Picture thickness (depth inside the frame)
• Connector width & length
• Screw hole diameter

📏 Default Settings

With default values, the generator produces:

• Frame size: 400 × 400 mm
• Backplate thickness: 2 mm
• Frame border: 15 mm wide, 10 mm high
• Picture overlap: 3 mm
• Includes mounting holes on the back

🖨️ Printing

• Designed to print as 4 separate parts
• Use “Split to Objects” in your slicer.
  Then press “A” or use “Arrange All Objects” to distribute the parts across the build plate(s).
• No supports required. Minor stray lines may form under the overhang, but these are easy to remove and do not affect the final quality.

Recommended:

• PLA or PETG
• 0.2 mm layer height
• 2 wall loops (tested), increase if extra strength is needed

🔧 Assembly

• Parts click together using the connectors
• Can be glued for permanent rigidity (optional)

💡 Notes

• By increasing the frame depth, you can use it as a shadow box
• Connector fit may vary slightly depending on printer tolerances
• Slight sanding may improve fit if needed
• Add a small tolerance (0.5–1 mm) to your picture size for easier fitting.
