Magnet Holder for Fridge/Whiteboard - ADJUSTABLE!

🧲 Custom Magnetic Holder – MakerWorld Editor Guide

Create your own magnetic holders (a.k.a. magnet tabs or whiteboard pins) that perfectly fit your disc magnets! This MakerWorld-compatible model lets you adjust the size of the magnet pocket with just two inputs—no coding required.

🛠️ How to Use in the MakerWorld Editor

Once you open the file in MakerWorld’s OpenSCAD Editor, follow these steps:

1. ✨ Adjust the Magnet Size

In the Customizer panel on the left:

• 🔘 magnet_diameter_input
  ➤ Enter the diameter of your magnet in millimeters
  ➤ Example: If your magnet is 12mm across, enter 12
• 🔘 magnet_thickness_input
  ➤ Enter the thickness (height) of your magnet
  ➤ Example: For a 3mm thick magnet, enter 3

💡 You don’t need to add extra space for fit—this model automatically adds a tolerance of +0.2mm (diameter) and +0.25mm (thickness) for a smooth press fit.
