CAD from a Physical Sample: Calipers, Not a Phone Beauty Shot
The from-photos page exists. This service is the physical master on the bench: we caliper OD, depth, and island width so CAD is not a guess from a cropped PDP.

We do not reverse-engineer a tray you bought on Amazon
If the sample is not your IP, we stop. Photos of a competitor listing are not a master. From-photos still needs a ruler in plane. This service is when you can send or show the part.
What a caliper catches that a phone hides
Units in millimetres. Inch STLs that scale 25.4x are a different failure - name units in the email.
| Measure | Why |
|---|---|
| OD | Listing inch vs tray mm |
| Depth | Photos compress depth |
| Island width | Tear risk |
| Undercut | Split vs flatten |
Drawing deposit about $50 USD when we must model
If we already have a solid STEP, we may skip it. If we remodel after a units miss you catch on the sample, we will say so before a second CAD loop.
How to ship the master
Say whether we must return it. Pack so corners do not crush. Photos on arrival. Pour chemistry. Qty.
FAQ
Is this the prototype hub?
No. Prototype is after CAD lock. This is how CAD gets millimetres from a part.
MOQ?
20 trays once we cut production. Modeling is not the 20-tray lot.
Can you work from a 3D print master?
If it is stable. We still caliper. See the 3D printed master blog.
