Where to buy premeasured, precut, prebent breadboard wire?

At various lengths and the ends already bent at right angles?

 

Basically want to shorten time in lab significantly cutting wires and then realizing I am a bit too short or a bit too long if I want to stay relatively flat, neat, and compact. And use more straight flat wire connections than large rainbow archs.

It is true that the number of lengths are great but for densely packed and relatively simple breadboards you may use lengths of 2,3,4,5,6, 7 pretty often

I know I could sit down for a few hours and try to crank out some wire lengths

Perhaps not wires but solid plastic or rectangular shapes of this exist?

I feel like something like this should exist. If no one has heard of it here, I might look around a bit more often

If anyone would like to say "do it yourself/get better at eyeballing/cutting fast" I can't disagree with that at all and of course that it was I am doing now but I'd appreciate it if that wouldn't be posted here so I can continue the search and the forum thread doesn't autodie at the first "just get better at cutting" message.

 

1. Is there another name for that?

2. What allows the thing you mentioned to reliably create same length stripped wires and bent 90 degree metal ends?
