Stackable Woodworking Setup Spacer Blocks (Standard)

I had planned to just print a simple setup block that I saw someone use in a YouTube video.  It was 1"x2"x3" and seemed handy to have around.  As I started modeling it up in Onshape, I decided some other sizes would be useful as well.... but THEN, I decided to make them stackable for easy storage.  (Ain't gonna lie--there were some challenges, as I worked to dial-in the exact snug fit I was going for, but also not so tight that other tools were needed to get them apart, which wouldn't be very useful/helpful at all.)

This set will give you quick and easy access to the following (12) measurements:

3 in, 2.75 in, 2.5 in, 2.25 in,

2 in, 1.75 in, 1.5 in, 1.25 in,

1in, 0.75 in, 0.5 in, 0.25 in.

Oh, You can also use the push-holes as simple templates to draw 1in, 3/4 in, and 1/2 in circles on a surface.

I printed them using a light-color filament and then colored-in the recessed measurements with a black permanent fine tip marker.  If you prefer NOT to have the measurements recessed (0.5mm recess), I also included a set of .stl models that are unlabeled, so you can just write the measurements on them.  

If you want me to make a similar version in metric sizes, please comment below.  If I get enough comments, I'll probably get inspired to do that as well.
