Foam cutter

thingiverse

simple scalpel blade foam cutter for use primarily with 5mm foam board. This is a remix of https://www.thingiverse.com/thing:2719562 which I found to be a good idea but was impractical in that it required enlarging the hole in the stainless steel blade and there was no clear means of adjusting the blade. This design uses a sliding blade holder which grips the blade tightly on the slider with a small 2.5mm or similar screw and is able to move smoothly to adjust depth or move blade safely for storage.
