How to use:
With the magnets facing the surface (floor, table, etc), slowly sweep this device back and forth hovering somewhere between a half inch to 2 inches above said surface. Let the power of the 8 N52 magnets arranged in a Halbach array do the work for you and find those hard to spot, hard to replace, springs and other ferrous components.
Assembly instructions:
Before reading these instructions, just be aware of the goal here. We are trying to create a specific Halbach array arrangement where one pole (N or S) is always pointing in the direction away from the center of the Spring Sweeper, and the opposite pole inwards.
Refer to the “k=1” arrangement here to see a visual example
- Place the Spring Sweeper model in front of you with the bottom (magnet hole side) facing up.
- Take 8 of the 3/8" N52 cube magnets and stack them end to end in one straight line.
- Pick one end of the row of magnets, doesn't matter which, and point it away from your body.
- Carefully remove the magnet farthest away from you, from the row, being careful to keep the face that was pointed away from you in that same orientation until the next step is complete.
- Push the magnet into the first hole (of your choosing), always keeping the face of the magnet that was pointing away from you in the same direction. That face should be the side closest to the outer edge of the Spring Sweeper model.
- Side note: This should be a tight friction fit. If it's too loose, or too tight, you may need to calibrate your printer or rescale the model a bit. The magnets should not be able to come out on their own.
- Repeat steps 2-5 until all magnets are inserted.
- If you have magnetic viewing film, the fields should look the same as the one shown in the pictures for this Printables entry.
Printing Instructions:
- 15% infill
- Any layer height you wish
- Multi-color to make it look nice (if you want)
- No supports needed
