Combination Square

Combination Square (also known as a Combo or Sliding Square) It can be quickly attached to ANY steel rule up to a max. thickness of 1.2mm. This is an extremely versatile measuring & marking tool with many uses, but the main ones are shown in the images here. 1. Marking 90 degree Lines2. Marking 45 degree Lines3. Scribing Parallel Lines4. Depth Gauge MeasurementI particularly wanted this design to be:fully 3D printable versatile enough to accommodate existing steel rules, and so avoiding a printed rule component (which could never match in terms of resolution & accuracy).Robust! and so able to stand to a workshop environmentHold a steel rule securely with easy to operate clamping mechanism. This model is the result & I am really pleased with how it turned out. Super pleasant feeling in the hand in terms of tactility (but also its weight), accommodates all my steel rules, and its solid as a rock! Zer
