@dragonator -Did you made/3d print a template to hold pogo pins while soldering? How did you hold them straight? I already have recommended by you pins delivered and it seems like it won't be easy to have them alighted without template. I didn't tried to solder them yet as I don't have the rest of the components delivered.
Also did you try to use snap-in type of design of the HP45 carrier? I mean like the factory design if you know what I mean...

Re: Hacking the HP45
I used M3 screws and 3 5mm spacers to mount the 2 halves on top of each other. I did make a spacer around 7.5mm thick to put between the boards and the table, but that is only for the distance the pins should be, not the alignment. For that I only used the 2 boards. I would love to 3D print a mold, but the holes and spacing are too tight.
I am working on the HP45 controller page. On that I hope to include soldering instructions.
I have not yet attempted a snap in carrier like the factory. It is actually quite difficult and I have not yet made a design I like for it. The old one was good enough for now. I will look around for some inspiration when I have more time to design a better carrier.

Re: Hacking the HP45
Okay, I'll try to print a template with holes for pogo pins. I don't know if it's going to work but I did print finer details before. I will also try to print snap-in carrier. How detailed is your 3D model for HP45?

Re: Hacking the HP45
Contacts on the model are with a few tenths of a millimeter on the head I measured it on. For now it was accurate enough for me to make a carrier with. The tiny pieces of plastic on the top back are accurate within half a millimeter.
Re: Hacking the HP45
Printing the template is harder than expected. I have to find my .2 nozzle and try it again.

Hello,
here is a pic from the HP45 die and Kapton lasered Inkholes. There is another type of HP45 so called HP45(si)

if you need a special INK, you have to take a look at ......

Re: Hacking the HP45
Here you can see the comparison between the HP 45 on the left and the HP45si on the right. The SI is solvent based inks!

Re: Hacking the HP45
1. On the page (http://ytec3d.com/hp45-inkjet-printhead/) a schematic overview of the nozzle alignment can be seen. This is not correct, however, because on a genuine HP45 cartridge the nozzle orientation is (3,3,3,3,3,3,4)
2. I had thought to have read that you know only water-based black cartridges. With solvent-based cartridges, you could also use a different powder for the printer to glue ABS, for example.
3. I didn't know if anyone of you have ever seen the HP45si
