lab fixture 3d model

A precise, FDM-3D-printable laboratory strain gauge gluing and pressing fixture, actively engaged on a 20mm diameter polished steel tube section from image_3.png, which has its milled flat face upward. The fixture base is a simplified V-Block holding the tube fixed with two visible zip ties. A single, robust FDM-printable column guide gantry rises from the base. A standard COTS micrometric head with a simple thumbscrew is mounted at the top of the gantry column. At the micrometer's press-end is a modular, transparent acrylic fixture plate. Crucially, this transparent plate has a shallow, rectangular recess, precisely sized with a 18.2mm x 12.2mm fitment tolerance, designed to hold the 18x12mm HBM gauge detailed in image_6.png. An HBM strain gauge (with wires visible, matching image_6.png) is sitting in this precise recess, being pressed onto the milled flat of the 20mm tube by the micrometer. Clearly visible etched alignment centerlines on the base, gantry column, and the modular plate
