Dual CS2125 Turntable Inner Button

I got an old, but functional and nicely playing Dual CS2125 turntable. However, the moment I unpacked it and pressed the START button, I felt something inside break, making my new "fully-automatic turntable" a "somewhat-hopefully-semi-automatic turntable".

Turns out there's a small spring-loaded part the exterior button presses on, which then actuates the pulleys inside the turntable's mechanism, and it was just this little part which broke. Nothing some fumbling around in OpenSCAD (and a dozen print attempts) couldn't fix!

Nobody else in the world will probably see this, as I had a hard time finding out *anything* about the turntable in the first place, but just in case someone else has it, has the same problem *and* has a 3D printer, here is the solution.

Printed at 0.15mm, you might want to adjust the `$width` and `$hole_diameter` slightly, as these are the crucial parameters for a proper fit.

Cheers!
