⚠ Attention: Before printing the chessboard, download and print my Tolerance Bar model! Print it first to verify your printer’s tolerance and ensure the magnet will fit snugly inside the hole.
📐 General Dimensions
Total assembled size: 360 × 360 × 13.5 mm
The chessboard is divided into 4 modular parts, making it easier to print, transport, and assemble.
Designed entirely from scratch in Fusion 360, every detail was carefully planned to combine functionality, printability, and aesthetics.
🧲 Magnet System
Precision holes designed for 6 × 3 mm magnets.
Check magnet polarity before gluing to ensure correct attraction between parts.
Total required: 16 magnets (4 per corner).
📊 Tolerance Bar
⚠ Attention: Before printing the chessboard, download and print my Tolerance Bar model! This step is essential to find the correct hole size so your magnets fit perfectly without problems.
The tolerance bar includes:
Filament usage: ~4 g
Print time: ~15 minutes (on Bambu Lab P1S)
Hole sizes: 6.05 mm to 6.40 mm (steps of 0.05 mm)
Important: slice without rotating the model, to maintain test accuracy.
Use the same filament intended for the chessboard, since tolerance may vary depending on the brand, color, or type of filament.
👉 After printing, test the fit and note the best size. 👉 Select the chessboard profile that matches this measurement.
🖨 Printing Recommendations
Chessboard
Material: PLA+ or PETG
Layer height: 0.2 mm (or lower for finer finish)
Infill: 15–20%
Supports: not required
Chess Pieces
Material: PLA+ or PETG
Layer height: 0.16–0.2 mm for detailed finish
Infill: 10–15%
Supports: required
Supports appear only under the base of each piece, making removal quick and easy.
Once removed, the pieces remain clean and smooth.
🛠 Assembly
Print the 4 modular board parts.
Test magnets without glue to confirm polarity.
Secure magnets into the holes with glue.
Join the 4 parts to complete the chessboard.
Print the chess pieces and carefully remove supports.
⚠ Notes
Use super glue (cyanoacrylate) to secure magnets.
Ensure magnets sit flush with the surface.
Do not mix hole profiles: use only the one that matches your tolerance.
✨ This is a modular chessboard, designed from the ground up in Fusion 360 with every detail in mind — from print orientation, tolerances, and magnet alignment, to ease of assembly and a clean final look.
