LowRider CNC V4 Sharpie Pen Holder
This is a pen holder designed to fit the profile of a standard Sharpie pen body. It is a friction fit that leaves the pen tip extended about 60mm from the bottom of the holder. A gentle press fit allows for some “smushing” if you miscalculate the Z axis drop. It is designed to fit the LowRider Makita 65mm clamp. The slot on the top part is to allow a pen narrower than a Sharpie to be zip-tied in place.
The holder is helpful for accurate CNC squaring and trammeling, as well as making drawings.
It's a functional part, so any filament and and quality settings should work.
