MPCNC Sharpie Attachment

Here is a little attachment for the updated Multi-Purpose CNC machine tool holder https://www.thingiverse.com/thing:724999.

You can use a Sharpie Marker or pen or pencil to do the drawing.

You will need one or two 3x6 mm screws and washers plus a spring from the spring kit you can find at Home Depot. http://www.homedepot.com/p/Everbilt-Miscellaneous-Spring-Assortment-SP-9901/100142075?cm_mmc=Shopping%7cTHD%7cG%7c0%7cG-BASE-PLA-D25H-Hardware%7c&gclid=Cj0KEQjwhN-6BRCJsePgxru9iIwBEiQAI8rq80TpgVQ5vZSh9YOtsZPn6ybWt-3CetZ28zel043RhRoaAgyf8P8HAQ&gclsrc=aw.ds

The spring may need to be massaged to make it fit over the sharpie better. All of the springs in the kit were a bit too small to fit over the sharpie but you can bend one with a little bit of effort.

It is a good idea to sand down the ridges in the insert to enable it ride smoother inside the base. I also added a bit of lithium grease to lubricate it.

Place the spring over the Sharpie and Insert Sharpie into the insert
