3D printable iMac G3 replacement screen bezel

Hi all,
I recently worked on a 3D printable replacement inner bezel for the iMac G3. I think it fits quite well now, so the CAD and STL files have been released:

For the printing material I recommend ABS or ASA. Viability of PETG is still under investigation due to the temperatures it needs to withstand.

It's a work in progress, and I currently tested this only using my own printer. If you decide to give this 3D printed bezel a shot, feedback is appreciated.

Great work!!

Wow — did you scan it as a basis? How did you manage the accurate dimensions?

Mostly by taking pictures of the curves where it had to fit, using caliper measurements on the original bezel (I had the chance of having an intact one) and quite some trial and error.
I don’t have access to a 3D scanner, unfortunately.

Me neither… nice work, that's a massive effort!

Nice work. Have you tried Photogrammetry as a starting point for complex shapes? Painting a texture on it might help with that as the uniform colour and texture will make it harder to get good results.
