This is a replacement wrench for the Melissa & Doug Take-Along Tool Kit Wooden Toy (https://www.melissaanddoug.com/take-along-tool-kit-wooden-toy/494.html).
Design
I copied the main exterior and tool dimensions of the original wrench, but the curvature is slightly different. I improved the original design by adding a comfortable chamfer on the top and bottom.
Printing Instructions
Print as oriented in the .stl file. You probably won't need any supports or brim.
Notes
I designed the model in OpenSCAD and it's fully parameterized. If you'd like a variation on this with different dimensions, just message me.
The author marked this model as their own original creation.
