Bread lame with slide toggle

I use this bread lame multiple times a week for the scoring of my sourdough bread. nu_ha's design is awesome! The blade fits perfectly and the slide works very wel, also with use of PLA. The slide could come out however in the original design, since there is nothing holding it back. therefore I added a third magnet (and slightly altered the location of the magnets), to keep the slide in place while using the lame. Now the slide clicks between the two settings. I don't have 8mm magnets, but the hardware store nearby (Hornbach) had 6 mm diameter magnets. I incorporated those dimensions into the design. NB make sure the poles are aligned well when putting the magnets in. See nu_ha's instructions in the original.

Additional materials:
-3 magnets: 6mm diameter, 3mm thick.
-1 razor blade, see photo
-Glue for fixating the magnets

Tip: Printing with black PLA and using black magnets has a very nice result.
