Continuous 3D CAD Design for Electronic Enclosure

Ongoing 3D CAD Designer — Turn PCBs / Gerbers into Printable Enclosures

Overview

We design small electronics products and need a reliable CAD designer to produce 3D-printed enclosures for our PCBs. This is recurring work: we release new boards regularly and want a go-to person who can take a board and return a clean, print-ready case that follows our house standard.

The core deliverable

We hand you a Gerber package or native PCB file (EasyEDA .eprj, plus board outline, drill, and a BOM with LCSC / manufacturer part numbers). You return a finished enclosure modeled to
that board.

Our enclosure standard (what "done" looks like):

- Two-piece shell sized to the board, with correct wall thickness and internal standoffs/bosses for the mounting holes.
- Connector cutouts located and sized from the board footprint and connector datasheets — heights resolved from the part numbers in the BOM (e.g. RJ45, USB-A/C, Molex Mini-Fit power,
microSD, fan headers). Openings account for the mating plug shell and latch clearance.
- Lid retention via friction tongue-and-groove (≈0.15 mm clearance) or a glue-on lid, per board. A base nesting lip with a self-supporting 45° lead-in for registration.
- Wall-mount ears (M4) where applicable.
- Thermal venting (side-louver intake → top exhaust) for boards with an active fan/heatsink.
- Branded lid — our logo/wordmark inlaid as a 2-color feature (we provide the vector art).
- Design for FDM: parts must print support-free in a sensible orientation (no floating regions / long unsupported bridges), tuned for Bambu printers in ABS.

Deliverables per board:

1. Editable native source (Fusion 360 .f3d preferred; parametric so we can tweak).
2. Watertight STEP (for engineering) + STL + a 2-color 3MF ready to slice.
3. A short note on print orientation, material, and any test-fit tolerances.

You should have:

- Solid parametric CAD (Fusion 360 or equivalent) with real enclosure / DFM experience.
- Comfort reading PCB outlines, footprints, and connector datasheets to place cutouts accurately.
- Hands-on FDM 3D-printing knowledge (orientation, clearances, tolerances, multi-color).
- Bonus: EasyEDA / KiCad familiarity; experience designing snap-fit and gasket / IP-rated enclosures.
- Access to a 3D printer is a plus but not required.

How to apply — please read carefully:

To prove you actually read this and aren't an auto-bidder, do both:

1. Start your reply with the word "VIKING" (all caps, first word — bids that don't will be ignored).
2. Then, in your own words, answer this: Given a Gerber package and a BOM, how would you determine where to place a connector cutout and how tall to make the opening? One or two
sentences is fine — I'm looking for real reasoning, not a generic pitch.

Also include:

- 2–3 examples of PCB enclosures you've designed (renders + the board they house).
- Your typical turnaround per enclosure and your per-case price.

Generic copy-paste bids and anything missing the keyword get skipped. We'll start with one board as a paid test — a strong result leads to steady, recurring work.
