Improved magnetic separation rack for 12x 1.5ml vials, optimized for a pipetting volume of 200µl and greater. This version holds 12x vials, with bigger magnets and shorter distance to the vial, making the separation faster.
Requires 6x cylindrical ø10mm by 20mm axially-magnetized neodymium magnets (the stronger the better). One source:

Print 4x “plug”, 2x “half-rack”. No supports required. Optimized for 0.2 layers, 0.4 nozzle. After printing pair the two bodies, then connect by pushing the four plugs on the two sides.
Push firmly the magnets in the recess. Magnet orientation is important: the front-facing side needs to alternate between N-S. Follow this guide:
You can swap N/S sides as long as the alternation is maintained.
