Magnerds

NOTE: This solution is intended to be used with one or more manufactured products.

A Magnerd is a rubber band with a magnet attached. Printing requires flexible filament.

Taking measurements then trying to match the numbers in Customizer will probably yield unexpected results because the values are relative rather than absolute.

Tree-like supports (as provided in Meshmixer, Ultimaker Cura and Flashprint) work with the filaments suggested and can be used for the retainer ring aperture. I wouldn't recommend adding them to the inside of the barrel at any barrel size because they can be quite difficult to remove from inner surfaces. Don't expect supports to work if you try to print using a spongy filament.

My recommendation for a powerful but small magnet to use for Magnerds is [Michaels PROmag Neodymium.](https://www.michaels.com/promag-neodymium-magnets/10413548.html)
