Pen Holder MK7 (15 mm spacers)

I redesigned this in scad with a 15mm spacer instead of the 1/2 used on the original. My MK7 came with 5/8" mm spacers. Fits a Sharpie Fine Point just like to original thing.

I may add a "tab" to it that sits on the side of the heatsink to keep it in a more stable position.
