These components are optimized for machining with a 1/8-inch endmill bit. As one-piece parts, they feature precisely drilled holes designed to accommodate 10-24 or 10-32 bolts threaded to a .1495-inch tap size. To assemble these components, you will require 2.25-inch bolts for the 9mm, 12mm, and 15mm versions. If available, a 2.5-inch bolt can be used with the 15mm models as well. However, please note that these parts are not intended for 3D printing due to their tolerance specifications, which are tailored for CNC machines rather than Fused Deposition Modeling (FDM) printers. The accompanying image showcases the 44T 12mm version, machined from a hard resin wax as a sample and test-fitted for accuracy.
