Onboarding our first 5 hardware teams

PCB to enclosure
in 72 hours.

For hardware founders shipping ESP32, RP2040, and STM32 boards. Send your board files plus a quick brief — get a fitted, 3D-printed sample and print-ready STL back in 72 hours. $1,500 flat. Fully refundable if we miss the deadline.

The gap

Your board is done.
The enclosure is hell.

Every hardware founder hits the same wall after the PCB rev. AI 3D tools don't know what a USB-C cutout is. CAD freelancers don't understand connector heights or RF antennas. The agencies that do understand it charge $38K to $190K and bill multi-week engagements you can't justify on a seed budget.

So you do it yourself in Fusion 360 at 2 AM, and the print doesn't quite fit.

How it works

Three steps. 72 hours, end to end.

  1. 01

    Send the brief + board files

    Gerbers or board-outline DXF/STEP, plus connector positions, max component heights, and a few photos of the assembled board. No need to ship hardware — files are enough in almost every case.

  2. 02

    We model + iterate over 72 hours

    Parametric CAD templates per board class do the load-bearing fit work. One revision included. You see renders + STL before we print, so the physical sample isn't the first time you see it.

  3. 03

    Print-ready STL + the printed sample lands

    Print-ready STL files plus a 3D-printed sample (FFF or SLA, depending on geometry) shipped to your door. Editable CAD/STEP available on request, as-is.

What you actually get

Concrete deliverables.
No AI buzzwords.

  • Print-ready STL

    Manufacturing-tolerance mesh, watertight, oriented for FFF or SLA print. Ready to slice.

  • Physical 3D-printed sample

    Shipped to your door. FFF or SLA depending on the geometry. Verified against your board photos.

  • 3 angle renders

    Front, three-quarter, exploded. Enough to drop into a deck, a Crowd Supply page, or a Slack DM.

  • Mounting + cutout verification

    USB-C cutout fit, mounting hole alignment, connector and antenna clearance. Verified before we hit print.

  • Editable STEP on request

    Parametric CAD provided as-is on request. Not DFM-certified for production tooling — that's a separate engagement.

  • Honest re-print policy

    If the miss is on our model, we re-print and re-ship on us. If you provided bad dimensions, we'll quote a small revision.

Who this isn't for

Filter early. Save us both the call.

  • Mass production tooling

    Injection-mold DFM and production-grade STEP are a separate, paid handoff. v1 is fit-and-function prototypes.

  • Etsy 3D-print sellers

    If you're selling printed accessories on Etsy, we're not the right shop. We design for boards, not for resale.

  • Enterprise programs

    Multi-rev, ISO-compliance, certified suppliers — that's a real consultancy engagement at 10–100× our flat fee. Talk to Synapse or MistyWest.

Pricing

One number. No retainer.

The sprint

$1,500flat

PCB to a fitted, 3D-printed prototype enclosure in 72 hours. Print-ready STL + the physical sample, shipped. One revision included. Fully refundable if we miss the 72-hour turnaround.

Add when you need it

  • Production / DFM handoff+$500

    DFM-prep plus manufacturing-ready STEP for injection molding. Add when you've validated the prototype and are ready for tooling.

  • Color / material swap+$300

    Re-print in PETG, TPU, ABS, or SLA resin once the prototype is dialed in.

  • Batch print g-code+$400

    CAM g-code for batch printing on your machine. Useful when you're printing 10+ units yourself.

Questions

Asked & answered.

Do I have to mail you my board?

In almost every case, no. We work from your board files (Gerbers or board-outline DXF/STEP), connector positions and max component heights, and a few photos of the assembled board. We only ask for the physical hardware when the geometry is ambiguous — and even then, you ship one, we ship it back with the enclosure.

What if you can't deliver in 72 hours?

Then the $1,500 is fully refundable. No retainer, no setup fee, no kill fee on you — it's on us. We'd rather lose the engagement than ship a missed promise.

What board classes do you handle?

ESP32 (all variants including S3, C6), RP2040, RP2350, and common STM32 (F0/F4/L4/H7). nRF52 and ESP8266 on a case-by-case basis. If you've got something else, send a brief — we'll tell you within a few hours if it's in scope.

Is this production-ready? What about injection molding?

v1 ships fit-and-function prototypes — print-ready STL, not production-tooling-ready STEP. Once the prototype is dialed in, the production/DFM handoff is a separate paid add-on ($500). It produces a manufacturing-ready STEP and a DFM review for tooling.

Who owns the design IP?

You do. Once the engagement is paid, the design IP is yours — full transfer. We don't retain rights or list your design publicly without permission. Standard mutual NDA available on request.

What file formats do I get?

Print-ready STL by default. STEP/CAD available on request, as-is. Renders are PNG/JPG at 2× resolution.

FFF or SLA?

Whichever fits the geometry. FFF (PLA/PETG/TPU) for most cases — strong, fast, cheap. SLA (resin) when you need ≤0.1 mm tolerance, transparent windows, or a smoother finish. We pick based on your board, and the choice is in the brief response before any print starts.

Who pays for shipping?

We ship the sample to you in the US for free (USPS Priority or UPS Ground). International shipping is at cost — you pre-pay, we ship.
