Snap joints are designed to be a tight fit. Depending on machine calibration, some work may be needed with a utility knife and/or Dremel to make them fit. **The Board** • Dual extrusion • Ooze shield • No raft • No support • 80-100% infill • 0.3 mm layer height __Inserting Magnets__ 64 magnets are needed, so cycle time is crucial. This was my process. I started by gluing one magnet into a corner square and letting it dry completely. This anchor magnet helped quickly orient each magnet to face the same way. 1. Put a drop of glue in several squares. 2. Drop a magnet onto the anchor (see above). 3. With one hand on the board and tweezers in the other, slide the magnet off the anchor with the tweezers. 4. Grab another pair of tweezers and press the magnet into a slot. **The Pieces** I scaled these pieces up to 123% to fill out the squares better: https://www.thingiverse.com/thing:1288929 • 0.2 mm layer height • 100% infill • Support for knights and magnet slots • No raft I used a similar process for inserting magnets but only used one pair of tweezers and held the piece in my other hand. I applied felt circles as I glued in each magnet, allowing me to let them dry standing up. **The Box** • 0.3 mm layer height • 70% infill • Support for snap tabs • No raft
