Quick Table Saw Blade Height Gauge - Metric and Imperial

Another idea that can be 3D printed, based on a design by Matt Boley, found on Family Handyman. Link: https://www.familyhandyman.com/woodworking/table-saw-blade-height-gauge/
His write-up states:

"Quick and Easy Gauge - This gauge block is the quickest way to set the height of a table saw blade. This one is made from a 3-in. length of 4×4 cut to the settings used most frequently. If you need more settings, just create another block.
Then when it’s time to reset the table saw blade, these blocks will help you get the job done quickly."

Again, I didn't have any suitable wood offcuts, so decided to design quickly for printing instead.

NOTE: I have not printed yet, but the shape/size/etc seems to fit the link details. I ran the STL's through netfabb and also verified the model completeness in Simplify3D (S3D), so it should print fine.

I suggest printing in ABS or PETG, but PLA will also be ok (I'll be using PLA+) - I would further suggest extra wall thickness, top and bottom solid layers (3-5) and medium infill percentage (20%+ honeycomb) to ensure rigidity.

I have included STL's with:

1. both metric and imperial blocks
2. metric block on its own - 5mm/10mm/15mm/20mm
3. imperial block on its own - 1/4", 1/2", 3/4", 1"
   -- this should facilitate quicker printing or if you need to replace at any stage

Each gauge dimension is approx. 90mm x 90mm with an overall height of approx. 50mm.
(equivalent to a 4x4 piece of wood, as close as...); the height was reduced so as not to waste filament...

I have included the Sketchup SKP file, should you wish to make other depths, etc

Comments welcome! :)
