Gridfinity Solder, Flux, and Tool Holder

This is a 2x2 Gridfinity organizer for some of my soldering materials. I use Kester 1lb rolls of solder, which are about 60mm diameter. I found dedicated solder holders are not space efficient, so I wanted a combo organizer. I also like to use a flux pen, which is about 14mm diameter. I made a 16mm hole for the flux. I also made additional holes for small tools, like tweezers. I use this along with other organizers on a 4x4 plate for cutters, water, solder sucker, wick, etc. I used a ½" dowel rather than print a post. I used Gridfinity Rebuilt just to generate the base plate and cube. I have yet to fully dig into this openscad project enough to fully understand it. It was useful to get started.
