magnetic fidget - parametric for any circular magnet

the fidget and its derivatives are enjoyable, but alas, i never have the matching magnets around. provided example models are for 3x1mm magnets stacked by two. this has been a lousy purchase. with this publication you can just edit the dimensions in the freecad spreadsheet instead of looking for matching models or spending unnecessary money. available options are magnet diameter magnet height - e.g. stacked minimum knob diameter if desired bigger than autogenerated by magnet dimensions number of positions per side exportable objects contain single knob double knob straight slide triangle square not all options may be meaningful, especially if the center lacks any magnets for bigger triangles and squares. prints without support and magnets are a supposed to be a press fit, but can be glued in as well if necessary due to the inbuild ribs.
