I noticed that my Dorai Sink Caddy was wobbling, turned it over, and one of the feet has disappeared.
As this is a $40 item, I don't want to just toss it.
So, I ginned up a replacement foot (it's the green one in the picture).
It's a loose fit, but usually the weight of the caddy will keep in in place.
At 0.5 g of filament (what's that cost? pennies?), it's certainly good enough.
The author marked this model as their own original creation.
