Magnet Storage Box (OpenSCAD)

Update

This design is superseded by the Version 2 remix.

-----------------------------------------------------------

With this OpenSCAD generator you can create a custom box to store your magnets.

To use it, simply set the magnet dimensions:

• The length of the box is set by your longest stack of magnets. {My box in the included files is 100mm.}
• This width of the box is automatically set by the list of your magnets. Enter a list of your magnet diameters (separated by commas) in the order you want and set the spacing between them. {My box in the included files uses 15,12,10,8,8,6,5,4,3 with 3 spacing for a total of about 100mm.}
• The height of the box is automatically set by the diameter of your largest magnet.

You can further tweak the box with these parameters:

• Choose a font, size, and style for the label on the lid.
• Set the overhanging lip height to keep the magnets inside the box with the lid closed.

Some advanced settings:

• Set a different hinge pin diameter.
• Set all of the critical clearances.

And some design aids:

• Rotate the lid open and closed to see the fit.
• Use the cutout feature to check the clearances.
• Individually de-select the lid or the base to see each part clearly.

When you are ready to create the STL files, you need to rotate the lid open and select the base and lid individually.

Slicing note

The hinge area should be solid - in PrusaSlicer set "solid infill threshold area" to at least 200 (see my 3MF file).

Printing note

I made mine with a 2 color lid to help make the size labels pop out. I used a font depth of .6 – but a light color over a dark color could probably use a larger value.

Design note

I went with a separate lid and base instead of print-in-place so you can create a bigger box that will still fit your print bed.

Assembly

This box is meant to use a piece of filament for a hinge. (see my tutorial). You may also change the hinge diameter (up to 4mm) and use a different material such as a rod or wire.

Using OpenSCAD and the Customizer

If you are new to using OpenSCAD and changing parameters, I’ve included my tutorial that may help.
