If you just want to fix it, I'd say cut/break the plastic away from the crimps, use two pairs of needlenose pliers to pull the pins out of the existing crimps, and put them into a new housing. If you're going to make your own cable, you'll also need crimps, good wire strippers, and a crimping tool: https://www.digikey.com/product-detail/en/jst-sales-america-inc/SPH-002T-P0.5S/455-1127-1-ND/

Get a lot of extra crimps if you go the make your own cable route. Really easy to mess one up and have to redo several if you want to get everything even. In particular you need to be extremely careful with the insulation part of the crimp, or it won't stay aligned with the other side as you crimp it. Took me about 5 tries to get my first good crimp and about 20 crimps to get a full connector with all good crimps and everything even. The tool I linked is the one I use, with the 1.3mm die for the copper portion of the crimp, and the 1.6mm die then the 1.3mm die for the insulation portion of the crimp. It's good enough I wouldn't spend twice as much for the engineer crimpers, let alone several hundred dollars for the "official" tool.

Honestly, if you go the make your own cable route, you're probably better off buying pre-crimped cables, and soldering your own USB connector.

man the price of the official crimper is insane.

FYI everyone. China has started making clones of the PA-9 engineering crimpers.

Yes it's inferior to the official but its on par with my $50 PA-9's.
Personally I use a combination of PA-9 and ratcheting style for my crimps

I got some of these the wires are only 22 awg but I can't find anything bigger. You would need a soldering iron but you could also just get this plus a crimp tool which would honestly be better I think.

Take a look at Youtube for simple tutorials. You could also change both the male and female ends to better connectors of your choice, just make sure you get the correct crimping tool. Cheers!

I would recommend the below laser, it works as described. Having a separate control module seems to be something of a personal preference based on the project, I mounted it on the X-Axis carriage above the laser.

I'm very happy with the below MKS-Base V1.6 (?!?) controller board. Apart from having to replace all of the Solidoodle connectors with JST-XH connectors it has been very easy to work with. There are a bunch of comments about various polarities being reversed, but I haven't seen it yet. I have not hooked up the LCD yet, which is one of the wiring concerns mentioned in the Amazon reviews.

This crimper is the bomb! I debated this unit (~$17) vs the PA-09 (~$40), and am extremely happy with my choice. The lack of reviews on this one made me a bit skittish, but I have another IWISS crimper that works well and I went with the brand recognition (and it's cheaper.)

Those ratcheting crimpers are garbage. The die has three slots, is way too wide and isn't properly sized to crimp both halves of these connectors. Something like this style gives you much more control over your crimps. People usually recommend the Engineer brand from Japan, but I can't bring myself to pay that much for them.
