Two wires into one...minus soldering

[LePaul]

I don't mind soldering...but I really like convenience too

Being an electronics learner...a step up from a newbie...I was thinking of using these

For the positive side block:

1. Left fan positive lead
2. Right fan positive lead
3. Positive lead to Ultimaker fan connector

For the negative side block

1. Left fan negative lead
2. Right fan negative lead
3. Negative lead to Ultimaker fan connector

Should work just fine

But soldering is convenient

From this side of the ocean we would typically use Wago's for solder-less connections, but in electronics I don't like that too much.

If it needs to be disconnected frequently I would use a connector (JST or whatever), and if not, I would solder directly.

But I'm old school and these things are probably working very well

I go with @Amedee - especially in environments where there is a lot of movement and vibration, nothing beats soldering. Try it, it is not that hard

Ok, so I need to figure out the best way to solder 2 wires into 1 (the two fan pos/neg into the connector wire pos/neg) !

[reibuehl]

Twist the two pos/neg coming from the fans, tin them by adding a little solder. Tin the other end too. Then slide the heat shrink tube over one of the two ends and move it out of the way. Now solder both (tinned) ends together with just heat. If you tinned the two ends well, you will not need any solder here, but you can add some. Then let it cool down and slide the heat shrink tube over it and heat that one up.
