Parametric 90 Degree Jig

Parametric 90° Corner JigThis is a fully parametric 90-degree corner jig designed to help you assemble perfectly square joints every time. Whether you're gluing panels, building boxes, assembling cabinets, or aligning frames, this jig keeps everything locked at a true right angle during assembly.The model is customisable to suit your needs. You can adjust the overall size, wall thickness, and internal corner dimensions to match different material thicknesses or project scales. Scale it up for large panels or down for small precision work.For optimal performance, I recommend using a 0.2 mm tolerance for proper clearance and a 3 mm wall thickness to maximise structural rigidity.FeaturesAccurate 90° internal angleFully parametric designStrong, rigid geometryCompact and easy to printSuitable for glue-ups, box builds, frames, and general woodworking alignmentPrinting RecommendationsPrint in PLA, PETG, or ABS3–4 perimeters for strength20–40% infill (grid or gyroid recommended)No supports
