Openscad designs for capturing powerful magnets (from old busted disk
drives) inside printed pieces that can be used to stick things to
refrigerators (at least ones with steel panels).

Naming conventions:

magN - each mag directory contains the files need to print
the parts for one magnet (mag1, mag2, maybe more some day).

frame - I call the metal the magnet is glued to the "frame"

mag - I call the actual magnet (attached to the frame) "mag"

back - The piece that has the shaped hole the magnet fits
into is the "back".

front - the piece that goes on top of the back and contains a
mounting slot for whatever custom thing is to be mounted to that
magnet.

Design technique:

Scan the magnets with flatbed scanner, process them in gimp to
eventually generate svg files that openscad can import to form
the shapes for the holes the magnet fits in. Gimp features
used: Lasso tool (with single clicks, not dragging), grow
selection, selection to path, export path (as svg). Also layer
flipping, rotation, movement, etc.
