I needed a small shim to stop my old windows from rattling, but this could be scaled up for anything.

MiniShim_v1 : The end comes to a sharp point. When printing at .2mm that small end is a bit thin and tends to break off, but if you're scaling this up that may be ok.

MiniShim_v2 : The end has been trimmed to 0.4mm height for better structure at the default size.

Width: 10mm
Length (Ramp): 32mm (Approx.)
Height (Ramp): 3.5mm (Approx.)

The length and height of the ramp are taken right up to where it starts to curve up for the tab.

You can choose to print it flat (default orientation) which will provide ridges at each layer, or you can turn it on its side for a smoother surface. I've found the ridges provide a better grip and prevent it from backing out.
