I already have the rear-bumper model in OBJ format and now need it production-ready. The main tasks are straightforward: create solid, accurate mounts on the top and both side sections (I’ll share exact dimensions and hole patterns) and then give the entire part a consistent 6 mm wall thickness. Clean geometry is critical because this bumper will move straight into manufacturing after your revisions, so please keep an eye on watertightness, proper filleting around the new mounts, and overall mesh integrity. When you finish, return the updated file in OBJ along with any native CAD you worked in; a short note on the approach you used to achieve the uniform wall would also be appreciated for my records. If this sounds clear and you’re comfortable manipulating surface and solid data at this level, I look forward to collaborating with you right away.
