It seems to me that the simplest way to make such rubbers is to cut a pair of discs with rubber sheets, bore six holes in each, alternating large and small diameters per the original pattern, and superimpose them back-to-back. The opposite sides are mirror-imaged, so it only takes superimposing the large holes over the small holes, and the rubber will be ready for installation. There is not even the need to glue the discs to each other, the compression of the screws will hold the discs together.
Does anyone sell a rubber flange for this columbia reproducer?

It's a bit more complicated than that. There's a perimeter flange as well as a raised center hub to account for.

Execellent points! Thanks!physicist wrote: ↑Sun May 02, 2021 9:56 pmThe simple answer to this is "yes" but there are limitations in the range of physical properties.
Most 3d printable synthetic rubbers are at the harder end of the range. It therefore depends
upon what sort of rubber is a suitable replacement to go in the soundbox.
If you were planning to make more than a few, it would probably be more cost effective to 3d
print a mould and cast the parts. There is a wider range of castable rubbers available.
