1-2-3 blocks are incredibly versatile and customizable drill press and milling fixtures. Their usefulness lies in the need for a precision-cut edge or fixed support surface. Traditional 123 blocks are constructed from durable, hardened steel that's ground perfectly square and flat. This particular setup block is designed to be cost-effective and disposable. For reference, similar steel blocks can be found on Amazon: http://amzn.to/28PFOgM. The dimensions of the block measure 1" x 2" x 3". Holes are strategically placed at a diameter of 5/16", facilitating effortless attachment to adjacent blocks or a worktable. When paired with step blocks (clamp set), these setup blocks truly shine: http://www.thingiverse.com/thing:50512. Here's how to assemble the fixture: For optimal results, print the parts with rectilinear infill at a minimum of 30%. It's essential to securely fasten the clamp by pressing a 5/16 nut firmly into place. To streamline assembly, consider purchasing a single 24" length of 5/16" threaded rod and cutting it into four 3-inch pieces, as well as two 5-inch sections.
