8-strip mag rack

A magnetic rack for 8-strip DNA isolation (or other magnetic bead applications). Works with standard 3" x 1/2" x 1/8" bar magnetics available on Amazon for a few dollars. The design doesn't require glue, and magnets can be recovered later. There's a high and low setting that works with the larger 200ul PCR tubes and the low works with shorter PCR strips. The design also handles those weird PCR tubes with connectors that extend downward and fits the 3 different tube designs we could find. The high and low settings are an homage to 10X Genomics very nice racks.

This is designed to be printed on it's back (put the big loop flat on the surface). Brim only necessary if you're having warping troubles in general.
