Me and my Dad bought a few Philco Transglobe B481 radios and used/junk parts to restore and fix them as a hobby. One of the junk parts that we bought had a main board that was not functional due to a capacitor leak that corroded the audio amplifier part of the PCB. The tuner part was intact and working. I replaced the affected capacitors and transistors, cleaned the traces and remade some where it was needed. The result was a completely functional radio that had a broken frame and no shell.
I decided to try making a new frame by doing a 3D model on Blender using the measurements of a good frame that we had. Being successful on creating that model and assembling the radio on it, I decided to buy a used shell for it and now this once doomed radio is a daily rocker.
I also modeled the band selector and tuner knobs, however I didn't print them yet.
Lessons Learned
Lessons Learned
With this hobby project, I learned how to make technical 3D models with measurements on Blender, preparing 3D models for printing and also a bit of electronics troubleshooting.

I modeled the radio's frame on Blender and printed it.
3D printed frame in PLA
Some parts of the 3D print looked a bit frail. That's because of the nature of PLA printing with thin walls. However, when mounted with the main board, that wasn't a big issue, as the board provided some strength to the structure.
The radio assembled on the printed frame
One of the measurements were slightly off, however I was able to assemble the main board on the frame without any issues. Since I was able to achieve my goal in the project, I decided to keep it as it is.
For my first experience in creating technical 3D models and printing, the result was really good.
