About this 3D model
The wrench from my set are shorter than the original upload. I edited the .stl by removing material on each end. The trapezoidal shape is 50mm to 80mm. Everything else is unchanged. It works with the original clip that I reuploaded along the modified part. Wrenches are a bit loose in the slots but clip is holding them in place. It could be fixed by scaling down the part in slicer or adding a bit of foam padding.
