Thank you for the step file, it worked a treat. I was able to create an additional dip tube pretty easily. for the reference of others, we used a 4mm extrusion with 5 degree ‘draft’ to approximate the existing dip tube inlet.
If any one cares, i managed to convert from stl to .stp using autodesk fusion 360. I first generated face groups (accurate), then i converted the mesh (prsimatic).
