How to make a development-board open frame with vibe CAD
Lay out a removable open frame around an unpowered development board while accounting for underside components, mounting holes and connector access.

mechanical layout for an unpowered low-voltage prototype, not an electrical-protection or compliance enclosure.
01 / START WITH THE REAL OBJECT
Measure before you prompt.
- Measure the board outline and the coordinates of each usable mounting hole.
- Measure component heights above and below the board rather than assuming a flat underside.
- Record connector housings, cable insertion paths and access to buttons or headers.
- Measure the intended fasteners and choose hole clearances through a representative coupon.
State units. If a dimension is missing, have your agent ask for it.
02 / GIVE YOUR AGENT A CLEAR BRIEF
Copy this into your CAD conversation.
Use Claude or another agent with a CAD tool such as OpenSCAD, CadQuery or your existing modeler. Fill in your measurements and keep the source editable.
Model an open frame using board_outline, hole_centers, underside_keepouts, top_keepouts, connector_envelopes, standoff_height and fastener_dimensions. Keep the center and sides open where access is needed. Ask for missing component heights and mounting details. Do not assume standard board dimensions or place supports under unknown components.03 / INSPECT AS YOU BUILD
Model it in deliberate steps.
Build the reference assembly
Draw the board and add simple boxes for components on both faces. Mark holes separately from decorative silkscreen or unused board cutouts.
Place supports on known locations
Position supports only at measured mounting points or explicitly approved bare-edge areas. Connect them with low rails outside the underside component envelope.
Expose the working edges
Remove rails that obstruct headers or connector access. Keep the frame and board separate and export a section showing the underside clearance.
04 / VALIDATE THE FIRST PROTOTYPE
Check the fit and intended use.
- Compare the hole-center sketch with an actual-size paper tracing of the unpowered board.
- Inspect the underside section for contact with components, solder joints or protruding fastener ends.
- Plan a mounting-hole and support-height coupon before fabricating the full frame; no assembled fit is yet demonstrated.
Material
PLA or PETG can be considered for the geometry study.
