Train Whistle Remixed with Spray Paint Mask

A remixed version of the original train whistle https://www.thingiverse.com/thing:77183.

I adapted this for my running group (https://lh3.run). They wanted personalized tokens for their season passes.

From the original: I added a keychain hook, a trail arrow, and personalizations. I have included the FreeCAD file for easy editing of the words.

The original print is a bit large to hang around your neck, so I scale to 90%. Any smaller than that results in poor whistle performance.

The hook can support at least 15 lbs. I've been wearing my whistle on a lanyard for weekly runs for several years now and it hasn't broken.

Print with 20% infill and no supports. Works fine with PLA and PLA+.

The spray paint mask has an unintended hole over the short tube. I might fix that in later versions. For now, a bit of masking tape works fine.

You might need to play with the size of the mask depending on the tolerances of your printer.
