How to make a card sleeve sizing gauge with vibe CAD
Compare several empty card sleeves against labeled reference slots before sorting them into boxes. The gauge uses user-entered dimensions and open edges, helping distinguish similar sleeves without treating nominal package sizes as exact measurements.
Concept illustration. Customize the prompt and upload your CAD.
A sorting aid for empty sleeves, not a certified gauge or card-protection device.
01 / START WITH THE REAL OBJECT
Measure before you prompt.
- Measured outside widths of the empty sleeve types.
- Sleeve lengths and seam locations.
- Desired spacing between reference slots.
- Readable label size for the stored sleeve groups.
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.
Create an open-edge sleeve comparison gauge with sleeve_widths, sleeve_lengths, comparison_clearance, slot_depth, label_height and plate_thickness. Ask for missing measurements and the intended comparison method. Use short open channels with broad rounded entries and neutral labels. Keep sleeves empty during comparison. State that printed dimensions must be checked separately and that this is not a calibrated precision instrument.03 / INSPECT AS YOU BUILD
Model it in deliberate steps.
Define what is being compared
Measure the outside width of each empty sleeve including its seams. Keep that convention separate from the card size advertised on packaging.
Build short reference channels
Create shallow open-ended channels rather than deep pockets. Give the entry a broad radius so a sleeve edge is not directed into a sharp corner.
Label the references
Place the measured value and the user's group name beside each channel. Leave enough space that a sleeve in one channel does not cover another label.
04 / VALIDATE THE FIRST PROTOTYPE
Check the fit and intended use.
- Verify the source measurements and channel labels agree.
- Review one channel coupon with a spare empty sleeve before making the complete gauge.
- Inspect the exported dimensions with a separate measurement tool after fabrication.
