- ✓0.24mm acceptable for large bins
🧱Infill Settings
- ✓10-15% for standard bins
- ✓20-25% for baseplates
- ✓Grid or gyroid pattern works well
🧵Materials
- ✓PLA - great for most indoor use
- ✓PETG - heavier items, workshop
- ✓ASA/ABS - extreme durability
🔄Print Orientation
- ✓Bins: open side UP (no supports!)
- ✓Baseplates: flat on bed
- ✓Tool holders: check for overhangs
📐First Layer
- ✓Use 5-8 bottom layers for strength
- ✓Calibrate Z-offset carefully
- ✓Slight elephant foot is OK
🧲Magnets
- ✓6×2mm N52 neodymium magnets
- ✓Press-fit or superglue
- ✓Watch polarity! Mark North side
💡 Pro Tip: Calibrate First!
Gridfinity tolerances are tight by design. Before printing your first baseplate, make sure your printer is calibrated. A quick XYZ calibration cube can save hours of frustration. The bins should slide in smoothly but not wobble.

Frequently Asked Questions
What is Gridfinity?
Gridfinity is a modular storage system created by Zack Freedman that uses a standardized 42mm grid. It allows you to 3D print interchangeable bins, baseplates, and specialized holders that all fit together perfectly.
What size are Gridfinity bins?
Gridfinity uses a 42mm × 42mm base grid unit. Bins can be any multiple of this size (1×1, 2×1, 2×2, etc.). Height is measured in 7mm units, with common heights being 3u (21mm), 5u (35mm), and 7u (49mm).
What magnets do Gridfinity baseplates use?
6mm × 2mm neodymium magnets (N52 recommended) are the standard for Gridfinity. They press-fit or can be glued into the baseplate and bin bottoms.
Do I need supports to print Gridfinity?
No! Gridfinity bins are designed to print without supports. Print with the open side facing up. Only specialized holders with overhangs may occasionally need supports.
What material should I use?
PLA works great for most indoor use. PETG is better for workshop environments with heavy items. ASA or ABS offer maximum durability for demanding applications.
Are Formd Gridfinity files compatible with other designs?
Yes! We follow the standard Gridfinity specifications. Our bins and baseplates work perfectly with designs from Printables, Thangs, and other community sources.
