Compact Multi-Size Wrench

In many workshops the same problem always appears: wrenches disappear exactly when you need them. Instead of searching for the correct tool every time, I designed a compact multi-size wrench that combines the most commonly used metric sizes in a single 3D printed tool. This wrench includes six of the most frequently used metric sizes: 8, 10, 12, 13, 14 and 17 mm These dimensions were chosen because they cover a large portion of everyday hardware used in: general workshop work automotive repairs furniture assembly DIY mechanical projects Why these sizes? The selected sizes correspond to very common bolt standards: Including both 12 mm and 13 mm is particularly useful because many automotive components use different standards for M8 bolts. Design Goals The wrench was designed to be: compact strong enough for light mechanical work easy to print convenient to keep multiple copies around the workshop By printing several of these tools and leaving them around the workspace, you will almost always have the correct size nearby. Specifications Length: 165 mm Thickness: 5 mm Material: PETG Sizes: 8 / 10 / 12 / 13 / 14 / 17 mm Type: Multi-size metric wrench Printing Settings Recommended settings: Material: PETG Nozzle: 0.4 mm Walls: 4 perimeters Infill: 30% gyroid Layer height: 0.2 mm PETG offers a good balance between strength, flexibility and durability, making it suitable for light-duty workshop use. Tip Printing several copies and placing them around your workshop or toolbox ensures you always have a wrench available when needed.
