Keychain based on the iconic primary mirror of the James Webb Space Telescope. The geometry is simplified. The sides of the mirrors should theoretically be black. However, I decided to print them entirely in gold so the color transition wouldn't be too visible. Update: I've had it on my keychain for over a year and it still looks great! Print Settings Rafts: No Supports: No Resolution: doesn't matte Filament: / PLA black and gold Notes: Use the "Pause at height" script in Cura to change filament mid print. Category: Keychains
