Jig to hold a knife to fiber laser. Has holes for 6mm screws and also for 6mm x 2 magnets to hold blade. smaller 2mm holes are for screws to drop into and position the blade as a stop position. The plate is to hold blade down if handle is too heavy. let me know if you need it changed to suit. Press magnets into the holder slowly and with out too much force. You can see where I got over zealous with one. I've upped the fill to help prevent this. (original was 15% fill and 2 walls.
