ALIEXPRESS has 16mm rubber or silicon balls, black or white. Delivered price about $1 each (10, up to 50 quantity).

You would have to add your own colour and line & attachment. All i can think of right now

Ronald:
Congratulations on your bumpers.
Great and very accurate idea.
😎

I heard from Aimee (model miniatures) about the bumpers she makes:
“The ball fenders I make have a hard top, typically with a brass eye for the tie off.
The balls themselves are a soft rubbery polyurethane. 4 bulbs $12 USD plus postage.”

I also received a spl from Edmund Faulkes to make 3D printed bumpers though the material requires soft material to make a “ squishy “.

I made mine using the bulb from a soft polyurethane siphon and a dowel shaped in a pencil sharpener. I drilled a 1/16” - 2mm hole in the center of the dowel to secure a cord in the dowel before gluing it in the bulb.

It doesn’t have the same final shape as Aimees but since it is meant to resemble a bulb, I will use it.

Excellent workmanship here. The real things are. Sometimes referred to as poly forms.
