perfect for me! kind of my first real print(in PLA) - easy!

Printed very well with supports on my MK4 with a 0.4mm nozzle and the standard 0.15mm Quality profile! Used Prusament JetBlack and P-Orange PETG.

Works great and managed to keep everything together without any screws by using the power/usb cables!

Printed with Sunlu PLA in Red and Black. I had a little bit problems with warping, as you can see on the picture. But the case works anyway.

Turned out really nice. Perfect fit!

A very solid design overall, but with one flaw that may or may-not keep it from working for you: It seems to be largely incompatible with most Z-axis brace designs.

If you have a brace to make your Z-axis more rigid, this will force this case to sit higher on the Z-axis, because the mounting clip wraps around the Z-axis. While this doesn't prevent the case from installing, it does mean that the X-axis servo cables are likely to catch the case as the X-axis ascends the Z-axis (assuming your X-axis cables are routed in the stock configuration). This can cause considerable strain on the cables if you aren't paying attention, and potentially break them.

I've thought about how to fix this issue, and I can only think of a couple of options:
1. Modify your X-axis servo cable routing (possibly for a cable chain design)
2. Modify the t-slot clip so that it will sit securely at the top of the Z-axis (possibly via another clip that would wrap over the top of the axis, to keep it from sliding down)

Again, solid design and I really like it. Just giving a heads up to anyone who has a Z-axis brace of any kind: if you want this particular case, you'll need to either already have additional mods in-place for improving the cable routing, or will need to modify the clip and be cool with your Rpi at the top of the printer, instead of the bottom.

Note: if you have one of the newer Minis that comes with a Prusa sticker pre-applied to the Z-axis, and you installed that particular piece of t-slot as pictured in the instruction manual, with the sticker on the bottom, outside position (instead of, say, the top of the z-axis), that will also interfere with the mounting clip in this model. For me, I have both a z-axis brace and that sticker, so I am going to see if I can figure out some way to redesign the clip, but I suspect mounting my RPi above the electronics box will make the most sense in my case.

@m_browne_147073 I'm interested in knowing about any solution you come up with, because I'm also running a MINI with the same brace and squash feet mods.

@LoremIpsum_246805 I actually found this one:

But I am not sure it is worth the added complication of just printing the original squashball feet and this pi 4 case:

Either way, it seems that the only solution is to mount the pi above the rest of the electronics, rather than on the Z-axis.
