Roxon Flex Companion Scale with Pen and Tweezers

This model is based on Energizer_98's model of a replacement scale for the Roxon Flex Companion. I improved the fit of the pen by adding a cap that snaps into place against the scale so that it doesn't fall out. I also added a version that includes a ruler on the side with 1/8" marks starting from the bottom of the tool when placed upright. It should be useful for measuring bolts and screws. 

The pen cartridge and tweezers are from Roxon's “Pen, Tweezers & Needle” tool

but you can also use these cheap pen refills from amazon found here:

Just glue the top of the pen into the pen cap with some CA glue and the cap will keep it secure in the knife scale.
