Parametric SMD Stacking Magnetic Mini Spools

A stacking, configurable mini spool for holding random lengths of SMD tape. There's space on 3 sides for labels. Top has a cover peeler and retention, and in the default size, enough space to dispense several components at once. Useful for hand PnP with vac pickup tool.

For 0805 passives, I think it holds up to about 500 for the 50x58mm default size. Tape with taller components will fit less, and larger components make not be able to wound as tight. The spool part is more of a cover to keep the tape from falling out.

The 12x3mm might be the size I've used for 5050 LEDs.

I find that the easiest way to load is to thread front end of tape in to the top slot (feed holes towards open edge) and coil tape in to case from outside end.

The 50mm width was chosen to fit within the small drawers of a [Akro-Mils 10144REDBLK](https://smile.amazon.com/gp/product/B01MAV3GQ6/) storage cabinet.

Magnets are 3mm dia, 4mm tall. Magnet diameter is also a parameter. When installing, make sure
