Pigma Micron 6 pen holder

This is a pen holder for pigma micron pens.  the bottom space is for weights if desired. I used two Ezisoe 1 oz stick on wheel weights that are 7.9mm thick,  34.3 mm long and 20.9 mm wide. 
 

The model is 140mm in length and 40mm high.  The hole diameter is 10.75mm.  Print with support on build plate.   Also printing with a brim helps adhesion and prevents warping.
