Why My Prototypes Have Version Numbers
Because “final_final_FIXED” stops being funny the moment two different parts are sitting on the bench.
I have absolutely used filenames that amount to “final_v2_fixed_really_final”. Most people who build things on a computer have. At some point it stops being funny and starts becoming a risk.
3D projects make this worse because the model is only part of the release. There can be source CAD, generated meshes, slicer projects, screenshots, print settings, build notes and the thing I actually uploaded publicly.
Once a design starts going through physical validation, “which one is the latest?” is no longer a good enough question. I need to know which exact geometry produced the part in my hand.
What changed for me
I started treating hobby projects more like small engineering releases. Not enterprise change control. Just enough structure to answer basic questions later.
What was this version trying to prove? What changed from the previous one? Did it print? Did it fit? Did I withdraw it because the design was wrong, or because the printer had a bad day?
That last question matters. If five mechanical variables change at once and the next print fails, I have learned almost nothing.
The useful minimum
A version number, a short changelog and one canonical project file are enough to remove a surprising amount of confusion.
The benefit is not that the folder looks professional. The benefit is being able to return three weeks later and understand why V0.2.5 exists instead of blindly repeating V0.2.4.
Future me is basically another developer joining the project with terrible documentation. I am trying to be slightly kinder to him.
