Repair Part Test-Fit App
Helps repairers scan a break or interface, adjust fit clearance on an iPad, and export a part model for test fitting.
This iPad modeling app is for people repairing furniture, housings, or small-appliance parts. It starts with a scan of the connection area and generates an adjustable mating part. Users capture a pass around a break or gap, and the first screen immediately highlights places where the part will not insert, may wobble, or lacks wall thickness.
They can then drag clearance, clip depth, and screw holes with a finger while cross-sections change color in real time, without first learning a full CAD command set. The app can also generate versions for different print materials; after a test print, users record “too tight” or “too loose,” and the next version converges from that feedback.
Rather than creating parts from a blank canvas, it handles scanning, fit assessment, and test-fit iteration around a real interface.
Why now
PixyCAD launched on Product Hunt on July 16, 2026. As of July 18, 2026, 00:33 UTC, it ranked #4, and the product already combines native iPad solid modeling, Apple Pencil input, and print-format export in one workflow. S1S2 This means that scanning a real interface, directly adjusting fit, and test fitting can build on an iPad modeling and 3D-printing workflow users already understand. This is a timely moment to test demand through a repair-specific entry point.
Target user
Repairers, makers, and small repair shops with a home 3D printer or access to printing services. They use it when an original part is unavailable, a housing has broken, or an existing model does not fit, and they want a test-fit part quickly rather than a general CAD learning curve.
Minimal entry point
Start with imported or captured STL and OBJ scan meshes only. Let users mark a connection area, adjust uniform clearance and wall thickness, and export a printable STL. Do not build full CAD, automatic clip generation, or material simulation yet.
Punching above its weight
Build searchable repair-case pages around “replacement part name + device model + STL,” and let users publish model versions from before and after test fitting. Real repair cases can continuously bring in target users from search and existing 3D-printing communities.
Competitors & gaps
- Shapr3DGoogle
- Shapr3D can already import STL files on iPad and build housings with mating features around meshes, but its workflow still requires users to understand sketches, shells, offsets, and Boolean operations. This idea narrows those actions into repair terms such as clearance, clips, and hole placement.
- PolycamGoogle
- Polycam can scan on iPad and export mesh formats including OBJ and STL, but it does not export STEP or turn scan results into parametric mating parts for repeated test fitting. The opportunity is fit assessment after scanning and convergence through feedback.
- PixyCADGoogle
- PixyCAD already offers native solid modeling for iPad and Mac, Apple Pencil input, and print-format export, but it starts with general-purpose sketches and direct modeling. This idea focuses on real breaks and interfaces rather than competing directly for full general-purpose CAD capability.
How it makes money
Free for scanning and fit checks. Sell exportable test-fit project packs per project, with a subscription for frequent users that includes unlimited projects and material presets.
The case against
The strongest case against this is that breaks, hole locations, and thin-wall structures are highly sensitive to dimensional error. Meshes from ordinary iPad captures may not be accurate enough, so users may still need caliper measurements and manual reconstruction of critical dimensions.
