After years of printing things someone else designed. This is the first thing that I designed and printed myself.
I spent a couple hours learning FreeCAD and designed this pen holder for my spouse. They were super happy with it. If people want I can provide the CAD and STL files.
I got my son the first 3d printer in our entire family - last week. I have already borrowed it to make several things from scratch. TinkerCad is amazing for that.
I am genuinely surprised that you spent "years" before taking this step. Not even making any adjustments to stuff you downloaded?
For the past 8 years I have primarily printed things I found online for D&D and whatever was useful without modifying it, except for scaling of course. Anything more intimidated me because that was getting into an artistic realm that is way outside of my comfort zone. But recently I have been doing a lot of retrospective analysis and decided that I am not going to let my comfort zone limit me anymore.
