Oreo Whistle Keychain

Print parameters (as tested)

• 3 perimeters/walls
• infill doesn't really matter, the default 20% grid works

Notes

Prints without supports in less than an hour (or less than 30 minutes if your printer wasn't a potato).

Sound/volume wise it's around the same as the other 3D printable flat whistles, so pretty loud.
