I'd call myself a hobbyist, but that just dates me. I'm a maker in the process of unearthing a workshop that has sat idle for a decade. This has lead me to Gridfinity and pegboard prints. When I can't find what I want, I try to create it. I have an engineering background and some familiarity with older CAD packages, but I'm re-learning everything. OpenSCAD is my friend and I'm getting to know FreeCAD.
