Simple spacer blocks with options for metric and imperial in common measurement sizes. Useful for woodworking or other general projects. All blocks also have a small indent to mark the center in the y direction which can be useful for pencil marking the center of pieces.  All blocks are a standard width and depth and have a variable thickness which is labelled on the blocks top surface. Imperial spacers are 1 inch wide by 2 inches deep. metric spacers are 25mm wide by 50mm deep.

No special print settings. they are just simple rectangles and should not need any supports or brims.

The code used to generate these in openscad is available on github here: https://github.com/dduxx/spacer-blocks if you want to customize them or produce some thicknesses that i did not initially provide.
