Magnetic door latch I made for my printer enclosure, it uses these square magnets I got off ebay: http://www.ebay.co.uk/itm/50pcs-4mm-x-4mm-x-3mm-N50-4X4X3-square-strong-magnets-square-magnets-/332176633320?hash=item4d57452de8 I used a vice to press the magnets into place and also added some super glue, but don't think the glue is necessary.
