Fisher-Price Record Maker

A web app for creating custom Fisher-Price record player music discs. Takes one or two MIDI files as input and creates a 3D-printable STL file.

Features

• Upload one MIDI for Side A, optional second MIDI for Side B
• Auto-maps notes to the Fisher-Price comb note set with octave folding
• Generates a printable STL disc with curved center labels
• Progress indicators during conversion

Requirements

• Node.js 18+ (recommended)
• npm

Local Setup

cd /mnt/c/Users/Isaac/fisher-price/app
npm install
npm start

Open http://localhost:3000 in your browser.

Docker

Build and run

docker build -t fp-record-maker .
docker run --rm -p 3000:3000 fp-record-maker

Docker Compose

docker compose up --build

Then open http://localhost:3000.

Usage

1. Click “Select MIDI (Side A)” and choose a .mid or .midi file.
2. (Optional) Add a second MIDI for Side B.
3. Click “Convert to STL”.
4. Download the generated .stl and open it in your slicer.

Notes

• The disc label text comes from the MIDI filename (minus extension).
• The disc is modeled at ~121.16 mm diameter and 3.0 mm thickness (single-sided); double-sided discs are 4.75 mm thick.
• For best results, print with the disc laying flat (largest side down).

Troubleshooting

• If conversion fails, try a simpler MIDI (fewer tracks/notes) to verify your setup.
• If Cura reports an empty STL, ensure the server completed the conversion and re-download.
