a better detent

In my last blog I said "I need to work on a better, softer detent mechanism". Here it is:

It's assembled from five parts

of which only the pusher tip is 3D printed.

The screw is drilled and bored on my mini-Lathe to create a shoulder that retains the head of the pusher, then tapped for the screw that retains the low-k spring made of 0.2mm wire.

Four of them look like this when installed in the anticipating carriage.

That sufficiently reduces the torque needed to rotate the carriage digit wheels when all four carry warning arms are triggered simultaneously. Hopefully it also will work for a stack of 20 or 30 wheels!
