    Thanks for that!
    I do have the files prepared, heard of the water-jet cutting shop, but I was told that this particular one is not too precise. The thickness is 3mm, it's pretty hard for me to find an aluminum sheet, 3mm, good enough for my purposes
    Still searching though.

    How good are water-jet cutters with holes for M3 and M4 screws?

    Water-jet is quite precise with limitations: one being a slight taper on the edges and two, rough edges. Rough edge-surfaces is no big deal since it is easy to file and smooth with sandpaper. The taper across 3mm is barely noticeable. Slower cutting speeds can yield a perpendicular edge. But you pay extra for machine time.

    My source for industrial things is McMaster-Carr (McMaster.com). Annoying shipping policy where you don't know the cost until later, but they are fair about it.

    You want grade 6061 or 7075, and you'll have to settle for 1/8" thick. Most water-jet shops will carry their own stock of 6061-T651. Nothing on eBay?

    I have successfully tapped many M3 threads in material down to .06 thick of 6061 aluminum sheet. If you get 7075 aluminum (read: "stiffer"), you might be able to get away with .09-.093" thickness.

    For tapping water-jet parts, I always let them cut the nominal tap drill diameter of the M3 or M4 thread even though they taper. You can optionally locate the tap locations with the water-jet profile to serve as a center for a proper tap-drill operation. M3 is 2.5mm drill and M4 is 3.3mm drill.

    Again, a good shop can cut very precise parts. So can persistence and a hobby saw

    Thanks a lot for the info! Looks like I'm gonna use the last option

    The whole heater mech assembly, I'm looking to try the M6 upgrade but I don't want to take down my cube to do it. I figure I'll try and get a spare hot block and do the modification to it and just swap it out.

    I'm still hopeful... some modify and make frankensteins... some move on to other models... hoping some still have some usable carts/chips and are willing to sell... i just try to keep a note on the last page so my requests don't go missed...
