Magnetic 8-well PCR strip holder

A small magnetic tube holder for 8-strip PCR tubes.

The holder was printer on an Ultimaker 3 without support using PLA, 20% in-fill on 0.2 mm. I used neodym N45 magnets 5 mm in diameter and 8.47 mm in length. The magnet is strong enough to clear magnetic beads in under one minute.
