About the job
Title: Parametric CAD Expert Needed - 4-Part 3D Printed Device (Pack & Go STEP)
Budget: $400 Fixed Price
Project Overview:
Looking for a mechanical engineer to model a 4-part consumer device designed 100% for raw, unpolished MJF Nylon 12 (HP 3D HR PA 12). The design uses a 12-sided faceted polygon (dodecagon) exterior aesthetic. All internal mechanics, dimensions, and manufacturing clearances are completely pre-defined below. No R&D or industrial design exploration is required—this is strictly a high-fidelity parametric execution task.
Required Deliverables:
A complete "Pack and Go" ZIP archive containing:
1. Native parametric CAD files (SolidWorks, Fusion 360, or Inventor) with a clean, un-collapsed feature tree.
2. High-resolution universal STEP (.stp) files.
3. A copy of the software's internal Interference Detection Analysis showing zero clashing geometry.
Technical Specifications & Clearances (Mandatory for Raw MJF):
- Part 001 (Monolithic Body): 32mm OD Dodecagon silhouette. Features a smooth 14.00mm ID internal core barrel transitioning to a 30mm deep internal threaded section. Wall thickness must be ≥ 3.5mm.
- Part 002 (Integrated Dial-Plunger): Single piece combining a flush top dodecagon dial and a male threaded stem ending in a flat 13.60mm diameter piston face (providing a strict 0.20mm air gap clearance from the chamber wall). Thread profile must be a coarse buttress or square thread with a 4mm pitch and a minimum of 0.45mm total thread-to-thread... read more

Thread profile must be a coarse buttress or square thread with a 4mm pitch and a minimum of 0.45mm total thread-to-thread clearance. Main drive must hit a physical hard stop exactly 3.00mm above the base floor (allowing exactly 12.00mm of linear vertical travel).
- Part 003 (Bayonet Floor Cap): A flush-fitting bottom cap with a 13.60mm diameter raised floor platform. It must lock into the body core via an internal 90-degree bayonet twist track featuring a 0.25mm tracking clearance.
- Part 004 (Matching Funnel): A matching loading funnel with a dodecagon exterior. Top opening ~50mm wide tapering down at a steep 60-degree internal angle to a smooth 13.50mm OD / 11.00mm ID circular spout. The base must feature a counter-bored nesting lip to align flush with the body facets.
- Stress Concentrations: Apply a minimum of 0.5mm fillets to all internal sharp corners, specifically at thread roots and floor transitions. All threads must be fully modeled 3D physical geometry (no cosmetic thread annotations).
To apply, please confirm you have reviewed the specific raw MJF clearances and can deliver the native files + STEP in a clean Pack & Go archive. read less
