@bob-hepple on the beta group we are taking about that. There are some options. Github shows the model but it's quite much more complex than just that because is easy to get the parts but to get the connectors Crimped requires special tool that is very expensive. We are looking into shops that sell the molex 2 wires on usa/uk and molex mini 2 pins (XH 2.5 molex) for the 5v fans.

So yeah, I think the best approach is to make adapters so the user only solders the adapter without touching the um2 cables, this way it would be very easy to go back to a normal state without hiccups.

Hi Bob,

When I built my printer and I ordered all of those connectors from RS Component.

For each of the three fans (normally fitted with this one) connector type: PHR-2

P/N: 820-1466 (RS P/N) (Brand JST)

For this connector you'll need socet pins (6) type: BXH-001T-P0.6 P/N: 820-1529

The two feeder lines, 5V DC (for cooling upper part of extruder) and 24 V DC (for the two serial connected cooling fans). For this you'll need three male connectors type: B2B-PH-K-S(LF)(SN) P/N: 820-1422 (RS P/N) (Brand JST) These pins are to be soldered. So you'll need some proper heath shrink tube for insulation of the soldered pins.

Here's some direct link to RS for the parts:

If you tend to by the tools from RS, do not do that, they are extremely expensive and not worth that!

You can buy the same “standard tool” from China for 16.50 USD. Yes I did and had no problem, I’ve to say been using such tools for quite some years.. This tool can be used on “most” of the crimping connectors on Ultimaker2.

Here is a picture for your inspiration. :)

You'll see even the original RS parts is made in China!
