Got @HanJammer 's 3.5" CF-IDE drive bay printed for my Cx5x86 PC last week, got it installed yesterday. Unfortunately, it didn't go flush as I had hoped. I could shave a bit off the sides and push it in a bit further, unfortunately if I do that then the screw hole won't align. I can drill a new one with the Dremel, of course, but I'm a bit tpp lazy to do that today. Maybe on the weekend.
That's why the 3D Printing rule of thumb is "measure twice, print... at least twice."
I mean, I occasionally get things on the first try, but I print a fair number of partial tests to make sure things fit.
The socket 423 mount worked great, though, but I discovered that backplates are nowhere near as standardized as I thought - nowhere near as bad as AT motherboard mounts.
I made "bench standoffs" for AT, but obviously they can be used with ATX or Mac or whatever.
I basically just printed posts and rings and then used a tap and die set to give them threads (I even worked out a way to use a portable drill for them to speed things up).
I tried to make a universal AT backplane, but there are too many variations just in the motherboards I have to make anything that doesn't depend on variable position mounts - why the AT backplanes have slots in addition to holes on them.
If I 3D print a custom case I can build in mounting holes for that particular motherboard, but the longer the distance between printed points, the more likely plastic shrinkage or warping, even if not visible, will make things a hard fit. Maybe I need to snag a few trays from damaged minitowers.
*Too* *many* *things*!
