this is a remix of Allted's design. It allows to remove the tool with a simple screwed cap. (I can then keep the support in place to use the needle cutter mounted on the same plate.
Written in Openscad, so easy to mod !
To use this tool, just put the blade in contact with the bottom board, lower Z by 1mm or so to get the spring acting, rise Z and start the cutting path.
