I already have a near-finished pen concept modelled in CAD; what I need now is a fresh set of expert eyes to make sure the entire piece is truly production-ready. We will walk through the current files together—cap, body, cartridge housing, every component—then tighten up the look and feel while making certain the pen can survive daily use without cracking or warping. Your background in plastics, 3D modelling and manufacturability is key. I’m especially keen on: • Subtle aesthetic tweaks that give the pen a premium presence • Engineering adjustments that boost long-term durability (wall thickness, ribbing, material choice, tolerances) Deliverables • Updated, fully parametric CAD files (STEP or native SolidWorks preferred) • A concise design note or drawing pack flagging each change and its impact on strength or appearance I’ll send the current models as soon as we start; from there we can iterate quickly until everything is locked for tooling.

Hello, thank you for sharing details on your pen concept — refining an already-modelled design for production readiness, durability and a more premium feel is exactly the kind of product development work we enjoy. Our usual approach would be to first go through the existing files together, flag the components that need attention for wall thickness, ribbing or tolerances, and then work through the aesthetic and structural adjustments in a staged, iterative way with a review round before anything is locked. TRYGVE Studio works across architectural, engineering and interior design projects, with a background in CAD and product modelling using industry-standard tools. Given the scope described, it would help to see the current files and confirm priorities before finalising an exact price and timeline. Feel free to message us with the files and any specifics before awarding, so we can scope this accurately — https://www.freelancer.in/u/faisal8071 Regards, Ar. Faisal Saif

From your photos and CAD I can see this is a handheld device housing a touchscreen, PCBs, and an optical sensor assembly in the dome. The refinement work is two things happening at once: the aesthetic tweaks (parting-line placement, surface transitions, fillet consistency) that make it read as premium, and the structural engineering (wall thickness tuning, ribbing behind flat panels to prevent warp, boss sizing for fasteners, and draft for tooling) that keep it surviving daily use. Both have to happen together because a rib in the wrong place shows through a smooth exterior surface. My approach: walk through every component with you, flag each change with its impact on strength or appearance, then deliver updated parametric CAD (Fusion 360, STEP export) plus a concise design note per modification. As a mechanical engineer I do exactly this, enclosure refinement for electronics with DFM for injection molding. Send the current files and we can start the walkthrough.
