Piece / projectKeep the wardrobe. Replace the fitting.
A broken plastic joint became a reverse-engineering project instead of a reason to replace the whole wardrobe.

A lid that starts with the thread
A reverse-engineered jar lid with a 1/4-inch pitch and a translucent-blue prototype.
Documented April 2021From the workshop
Make a new part meet an old one
The April 2021 account identifies a reverse-engineered jar lid with a 1/4-inch pitch. The photograph shows the blue prototype fitted to the jar, making the interface itself the focus of the project.
The blue prototype
I used edge-glow blue filament because it made the printed lid look like a three-dimensional blueprint. I left the prototype marking visible in the photo because that is the part I actually tested on the jar.
Starting with the thread
The jar already existed, so the lid had to begin with the interface instead of the outside shape. I measured and modeled the 1/4-inch thread pitch in Fusion, then printed a translucent-blue prototype to test the fit. The edge-glow filament made the part look like a three-dimensional blueprint, which suited the prototype stage. I left the marking visible in the photo because that is the actual lid I tested on the jar.

Lid reverse engineering and prototype: Michael Pytlowany. Existing jar geometry supplies the mating requirement.
The photograph is not evidence of a seal, food-contact suitability, or canning performance.

Glass covers and printed PETG parts came together in an early Fusion-to-print project.
Piece / projectRC spoiler, different print strategy
A 1/32-scale RC spoiler became an experiment in orientation, splitting the part, and avoiding supports.
