Flux for enclosure design
Your board. Its enclosure. Designed by AI.
Flux designs the enclosure around the real board, checks every fit and clearance, and prepares the files to print, machine, or mold.
Edit the enclosure you have
Your housing files. Edited by AI.
Bring the housing from SOLIDWORKS, Fusion, or NX, or a STEP, IGES, or BREP file from any CAD tool. Ask for the change in plain words, for example "make it 8 mm taller and keep the mounting bosses in place". Flux changes the housing and saves a new STEP file and editable CAD code.
The request, as typed in Flux
“The holder must cover a much taller power supply. Make the bent side flange 40 mm deeper. Keep the 4.4 mm hole in the flange where it is. Then cut five 5 x 30 mm vertical vent slots in the new part of the flange, 15 mm apart and centered on the flange width.”
Parametric by default
Flux builds the enclosure as editable CAD code. Change the wall thickness or the mounting-hole spacing and the enclosure follows.
Back to your CAD tool
Export the full assembly as STEP and continue the work in the tool your team uses.
Capabilities
The enclosure engineer your board deserves.
Designs the enclosure around the real board
Flux reads the board outline, mounting holes, connectors, and part heights. It puts supports on the mounting holes and openings where the connectors are.
Checks every fit and clearance
Interference, space for each cable, screwdriver access, and worst-case and RSS tolerance stack-ups from the board to the lid.
Packs the whole device
Boards, battery, display, speaker, and wiring in one assembly. Flux places each part and shapes the enclosure around them.
Finishes it in real materials
Name the material of each part, from anodized aluminum and brass to clear acrylic, glass, plywood, and carbon fiber, and see it in 3D.
Moves the opening when the connector moves
Move a connector or a mounting hole on the board, and Flux updates the enclosure to match. Change the enclosure, and Flux updates the board outline.
Folds the flex board into the housing
Flux folds a rigid-flex board at each flex joint and checks its fit around the enclosure and battery.
Workflow
From a board to an enclosure you can build, Flux does the work.
-
Start from the board or a sketch
Start from the board in your Flux project or an IDF board from your ECAD tool. Add a hand sketch, a photo, or a dimensioned drawing, and Flux matches its shape and dimensions.
-
Design for the process
Two-part shells with snap fits and a removable lid. Injection-molded housings with draft, ribs, bosses, and a parting line. Sheet-metal covers with a DXF flat pattern. Hinges with a set opening angle. Screws, threaded inserts, standoffs, and fans come from the part library.
-
Verify
Air flow through the vents and fan, heat through the enclosure wall, and stress on the shell, before the first prototype.

Make it
Flux checks the part against SLA, SLS/MJF, CNC, sheet metal, laser cutting, and injection molding limits. Export STEP, STL, and 3MF, make dimensioned drawings with GD&T, and get quotes from Craftcloud, JLC and PCBWay 3D printing, Shapeways, OSH Cut, and SendCutSend.

Every kind of enclosure, from one AI engineer
Choose the process for your housing. Flux designs the shell and the features that hold the board inside it.
3D-printed two-part shells
Build a shell with snap fits and a removable lid. Export STL or 3MF for printing.
Injection-molded housings
Add draft, ribs, screw bosses, and a parting line. Flux checks the housing against injection molding limits.
Sheet-metal covers
Design bends and flanges around the board, then export a DXF flat pattern.
Hinged lids
Give the lid a hinge and set its opening angle.
CNC-machined aluminum
Design an aluminum housing, check it against CNC milling limits, and export STEP and a dimensioned drawing.
Fit checks Flux runs before you print
Check the board, housing, and assembly together before the first prototype.
Board-to-wall interference
Find interference between the board and the enclosure. Flux can adjust the board outline and part positions to keep clearance from the walls.
Connector openings
Check the space in front of each connector and align the openings with its position on the board.
Room for cables
Leave space for wiring and cables inside the assembled device.
Access to every screw
Check that a screwdriver can reach each screw in the assembly.
Tolerance stack-ups
Compute worst-case and RSS tolerance stack-ups between the board and housing. Flux proposes changes from the results.
Clearance under the lid
Use the board's part heights to set lid clearance. Update it when those heights change.
Airflow and heat
Simulate air flow through vents and fans, temperature inside the enclosure, and heat conduction through its wall.

One platform
The enclosure, electronics, and code share one project.
Design the complete device with one AI engineer. Mechanical parts, electronics, and firmware use the same project data instead of disconnected CAD applications.
-
Mechanical design
Fit the shell, brackets, and mounts to the board's holes and connectors. Import STEP models and use the same library for electronic parts, screws, and standoffs.
-
Electrical engineering
Develop the requirements, select components, capture the schematic, and simulate the electronics inside the housing.
-
Firmware
Write firmware for the device's board, then build, analyze, and unit test it. Supported examples include Arm Cortex-M, RISC-V, AVR, and Pico.
-
Manufacturing
Prepare outputs for production with current sourcing, costs, and quotes for the board, parts, and cables.
Collaboration
Review the housing and board together, in the browser.
Open one live design with your engineers, partners, and AI engineers. Work together without sending CAD files between people.
-

Questions about enclosure design.
Yes. Ask Flux to design an enclosure around the board. Flux uses the board outline, mounting holes, connector positions, and part heights. It aligns the supports to the mounting holes, adds openings for the connectors, and leaves space for cables and displays. See ECAD and MCAD Co-Design.
Yes. Upload the IDF 2.0 or 3.0 board file (.emn) with its part library (.emp). Flux imports the board outline, cutouts, holes, part placements, and part heights, then designs the enclosure around them. You can also import the board from Altium, KiCad, and other ECAD tools and continue the electronics in Flux.
Two-part shells, removable lids, snap fits, screw bosses, ribs, draft angles, parting lines, hinges, vents, battery compartments, and connector openings. Flux also designs sheet-metal covers and chassis with bends, flanges, and a DXF flat pattern.
Flux checks interference between the board and the enclosure, the space in front of each connector, and tool access to each screw. It computes worst-case and RSS tolerance stack-ups from the board to the enclosure and proposes changes. In the 3D view, you can cut through the assembly and measure any gap. See Fit and Clearance.
Tell Flux what changed. Flux updates the openings, supports, and lid clearance to match the new connector positions, mounting holes, or part heights. When the enclosure changes, Flux can update the board outline and move parts to keep clearance from the walls.
Yes. Flux simulates air flow and temperature inside the enclosure with vents, fans, and heatsinks, and heat conduction through the enclosure wall. It reports peak temperatures, outlet air temperature, and flow rates. See Simulation.
Yes. Attach a hand sketch, a photo, a render, or a dimensioned drawing in the chat. Flux matches its proportions and dimensions and builds the enclosure for the board in your project.
Flux checks the part against the limits of SLA, SLS/MJF, CNC milling, sheet metal, laser cutting, and injection molding. Export STEP, STL, or 3MF, create a dimensioned drawing with GD&T, and ask Flux for 3D-print, CNC, and sheet-metal quotes.
Yes. The part library has screws, nuts, washers, threaded inserts, standoffs, fans, and heat sinks with 3D models. Ask Flux to find the hardware and place it at the enclosure mounts.
Yes. Flux designs brackets, mounts, mechanisms, and complete products, and the electronics and firmware inside them. See Flux for mechanical design and Flux for electronics design.
The Teams plan is $500 a month with shared seats and AI usage units, and covers mechanical, electronics, and firmware work.
