This is a magnetically clasped derivative of a previous design, with the following changes.
Overall dimensions unchanged.
Still fits standard leather holster.
Nano USB slot replaced with slot for 2 X CR1225 batteries (for the cybertool lite)
Slot added for 2 X 10X2mm rare-earth magnets.
Cyanoacrylate glue works well to fit the magnets.
I chose to fit the magnets in opposing polarities at each end of the lid so that it won't fit backwards.
The lid now doubles as a magnetic screw/parts tray.
The back of the holder accommodates 5 X magnets of the above listed size, for scre/part pickup, or simply sticking it to a metal surface - these magnets help prevent the bits falling out too.
