20mm CO2 Laser lens holder

I wanted a better way to hold my CO2 laser lenses.  So I designed a magnetic holder that is bright and keeps all my lenses in one spot.  your going to need a bunch of 5x2.8mm magnets.  the 2 pieces have a lip that couple the base and lid together so they dont slide apart and require pulling them apart.  Stacking them though will allow them to slide apart with sheer force.  you can slide apart a whole assembly but you need to pull the assembly apart to access the lens.  it's designed for a 20mm lens but you could probably use something smaller as well.  I printed mine with the size printed on the side of the holder too.  Just add the text in your slicer.
