🧲 Magnet Size Accuracy Test Block

I created this Magnet Size Accuracy Test Block to help test the dimensional accuracy of 3D printed magnet slots while also functioning as a convenient magnet holder during projects and assembly work.

This tool is designed to help ensure magnets fit snugly and securely inside printed parts without requiring additional modifications or print setting adjustments afterward.

✨ Features
• Tests magnet diameter and depth accuracy
• Helps verify magnet fitment before larger projects
• Functions as a magnet holder during assembly work
• Includes small removal holes to help push magnets out if they become stuck
• Simple single-piece utility print

🖨️ Print Recommendations
• Recommended materials: PLA or PETG
• Recommended layer height: 0.2mm
• Designed for reliable FDM printing
• Ensure strong bed adhesion to help prevent warping
• Supports are generally not necessary

🧲 Usage Notes
This block is intended to help dial in printer tolerances for magnet-fitting parts and reduce wasted prints caused by incorrect hole sizing.

Small holes are included within the magnet slots to make removing tight magnets easier if needed.

🔧 Assembly
• No assembly required
• Simply print and begin testing magnet fitment immediately

📦 Additional Version
Need more magnet slots and additional sizing options?

Try Magnet Size Accuracy Test Block V2 for expanded functionality and more storage capacity.

🎨 Design Notes
I created this tool after repeatedly testing magnet tolerances across different projects and wanting a faster, cleaner way to check fitment accuracy before committing to larger prints.

Thank you all for your continued support as I continue learning, experimenting, and designing practical tools and utilities.
