I’m releasing 3D Setup Blocks: a fully parametric, two-color printable set for fast, repeatable machine setup in the shop. Each block is square in section—height equals width from 1–20 mm—and the kit adds angle gauges every 2.5° from 0° to 47.5°. Positioning is straightforward via two 8 mm locating holes for pins or dowels plus a parametric utility hole you can resize; use them to set table-saw blade height and router-bit depth or any precise stand-off without measurements.
