I also uploaded a step file so that you can modify the design as you want. If you just want to modify the height of the tool, I would suggest to use the built in function in the slicers instead of uploading the .step file on your preferred CAD software (just a tip. Your time, your choice. ;D )
The author marked this model as their own original creation.
