I never liked small scale wipers. I don't even like 3r axle wipers.
I do like plungers of Rivarossi O. Like a short rivet, just back it. (or in a plastic tube assembly like Kusans. )
A homespun ball bearing tip, spring, hollow rivet seems doable.
Actually, like tiny dowel hole mounted, ball tip, cabinet door stays... click!
Maybe not easy on the eyes or your install, but I like the performance and durability so far (four years?)
