CustomFit3D
Cup holder adapters sized to your exact car + tumbler
Every car's cup holder and every tumbler brand's diameter is slightly different, so generic "universal" adapters from Thingiverse either rattle around or don't fit at all. CustomFit3D generates a parametric adapter sized exactly to YOUR cup holder and tumbler — enter your measurements, preview the fit in 3D, print a free 3mm fit test to confirm before committing, then get the full STL/3MF + print guide for $4.99. You'll need your own 3D printer to print the files.
Hey PH 👋 Maker here.
I kept seeing the same complaint in 3D printing communities — people printing
a "universal" cup holder adapter and it either wobbles or doesn't fit their
tumbler at all, because every car and every tumbler brand is a slightly
different diameter.
So instead of one fixed model, CustomFit3D actually solves for YOUR exact
combo — you measure your cup holder + tumbler, preview it in 3D, and it
generates a parametric adapter (real OpenSCAD geometry, not an AI mesh) sized
specifically for your setup. There's a free fit-test print so you can verify
before paying for the final files.
Would love feedback, especially from anyone who's dealt with this exact
"close but not quite" fit problem. Happy to answer anything about how the
tolerancing/generation logic works.
