Safety first!

This is a push shoe or push stick for use with table saws, routers, etc. Use this instead of your hand to keep your stock flat and flush while preventing injuries.

There are four iterations for various needs:

-1/2" or 12.7 mm "thin" version is 5 mm thick (pushshoe.50.5.stl)--most versatile and shortest print time
-1/4" or 6.35 mm is 10 mm thick (pushshoe.25.stl)
-1/2" or 12.7 mm is 10 mm thick (pushshoe.50.stl)
-1" or 25.4 mm is 10 mm thick (pushshoe1inch.stl). 

It's fine to use a smaller version on larger stock, but you may not be able to use a larger version on stock smaller than the vertical clearance.

This is intentionally designed small to accommodate smaller printers and will print fine on a 100mm x 100mm bed (4" x 4"). Scale up or down as you like.

I assume no responsibility for any damage or injuries that may result when utilizing this thing.
