Fisher Price Record Creator plus Zelda's Lulaby

thingiverse

This is a couple of scripts for generating disks for the old school Fisher Price record player music box.I took the files from Tycho on YouMagine which were in turn based on the design by fred27 on instructablesI did a handful of tweaks to the scad generation to make it more FDM friendly, printing several experimental discs until I got something that played right and didn't jam. You WILL need to use a slicer which includes the Arachne perimeter generation: CURA and PrusaSlicer have this enabled by default now, I'm not sure about other slicers.I also fixed the bug in the python script to generate the output midi file properly so you can get an idea as to what the final record should sound like.Included is a disc (and source) for Zelda's Lullaby from Ocarina of Time which I used to verify the settings.zelda_record.scad shows how to make a list of notes which scad converts into an STL. It was created by running ./music2fp.py zelda_record.mid and then modifying the default text it generates.To make composing easier I've included all_pins.mid. This is a midi file which simply hits all the notes all at once. Use this as a template in your favourite midi editing software to know which notes are available.Also note this is for the original Fisher Price record player; the Sesame Street version has slightly different pins and may not sound right playing records created with these scripts.
