Instructions
*Drain Plug hole can be centered pretty accurately by making a small start with a 1/2" bit before drilling 27/64" (or 11mm) Final hole should be a nice free sliding fit for the Sharpie nozzle. *Red wire nut is the correct size, but will need diameter to be sanded down slightly to fit freely in the pipe. *The spring shown works well, any stiffer might be hard on the pen tip. I found this at local hardware spring selection drawer. (looks pretty common) * The only parts needing fastening are glueing the disks to the "pipe", the slip fit fittings should hold well enough for this application without glue. *****With JENNER update installed, the Z touch tool (below) is not needed.***** *The Z touch rod is important because the Shaper can't sense the surface with the light spring pressure. The rod should be adjusted to project about 5mm less than the actual Sharpie tip. The Shaper will then "Aircut" somewhere in that 5mm range. This might take a little adjusting. The all thread is 5/16" The coupling nut and short bolt at the top is to adjust the length so that the pipe cap can hold the rod in place during Z touch. There might be more elegant ways to do this, but I wanted to have everything accessible from the top. See also https://community.shapertools.com/t/shaper-pen-revisited/8893/7
