Get a 3D model on this graph?

GROUPS:

I want to do 3D printing on this graph. But the bottom does not have to be filled. Thank you for your help.

ParametricPlot3D[{{t, 1/2 (1 - Abs[t] + Sqrt[1 - t^2]), 
   1/2 (-1 + Abs[t] + Sqrt[1 - t^2])}, {t, 
   1/2 (-1 + Abs[t] - Sqrt[1 - t^2]), 
   1/2 (1 - Abs[t] - Sqrt[1 - t^2])}}, {t, -1, 1}]

It's one dimensional (a curve) so physical printing in 3D will be a challenge. Might be better to make it a tubular surface.

Thank you. I find this way. Improve it plz!!

a = ParametricPlot3D[{t, 1/2 (-1 + Abs[t] - Sqrt[1 - t^2]), 
   v}, {t, -1, 1}, {v, 0, 3 + 1/2 (1 - Abs[t] - Sqrt[1 - t^2])}, 
  PlotTheme -> "ThickSurface"]
b = ParametricPlot3D[{ t, 1/2 (1 - Abs[t] + Sqrt[1 - t^2]), 
   v}, {t, -1, 1}, {v, 0, 3 - 1/2 (1 - Abs[t] - Sqrt[1 - t^2])}, 
  PlotTheme -> "ThickSurface"]

What exactly do you want to improve? The object prints just fine with Mathematica:
