10-20-30 blocks

cults3d

These are a metric soft version of the machinist setup tool the 1-2-3-blocks. Instead of 1 inch, 2 inch, 3 inch-blocks they have a 10 mm side, a 20 mm side and a 30 mm side. They are used as a handy inspection or setup tool having three different lengths on each block and the blocks being perfectly parallel, square and sized to each other. A good example would be to use them to place parts on that need to be checked for squareness, or to be held parallel by being placed on both blocks of the same height 10, 20 or 30 side. Also can be used to just raise something up on each end the exact same height.
