Fully customizable magnet holder for whiteboards, fridges, or any metal surface. Built from a FreeCAD parametric design and rewritten in OpenSCAD for full browser customization on MakerWorld.

✨ Features

• Fully parametric — adjust everything via the Customize button
• 3 top styles: plain (no handle), spherical knob, custom text, or your own SVG logo
• Any magnet size — designed around a 49.5 × 19.2 × 4.9 mm neodymium magnet by default, but adapts to any rectangular magnet
• Rounded edges on all sides for a clean, finger-friendly finish

🎛️ Customizable parameters

• Magnet dimensions (length, width, height)
• Wall thickness & fillet radius
• Top feature: none / handle / text / logo
• Handle: knob diameter, total height, stem diameter
• Text: content, font (500+ Google Fonts), size, emboss or engrave
• Logo: upload your own SVG, size, depth (emboss/engrave), rotation

🖨️ Print settings (Bambu Lab P2S tested)

• Material: PLA / PETG / ABS
• Layer height: 0.2 mm
• Infill: 15 % gyroid
• Supports: none (flat bottom, no overhangs)
• Orientation: flat side down (magnet cavity facing up during slicing)

⏸️ Magnet insertion tip

This model is designed to embed the magnet during printing for a fully sealed, glue-free result.

In Bambu Studio, add a filament pause (or "Machine pause G-code") at the layer just before the top of the magnet cavity closes. 

💡 If you prefer the classic method, just print as-is and press-fit the magnet into the bottom cavity after printing (add a drop of super glue if tolerance is loose).
