Mountable Raspberry Pi Case

Raspberry Pi Case

I needed a case which I can mount on the side of my 3D printer, which is working on Klipper, and have everything managed. After searching for a bit, I discovered that there is nothing for an Ender 3 V2 Neo, so I decided to design my own. I'm not a professional designer, actually not even close, so every opinion, suggestion, tip or trick, are always welcomed and appreciated.

First of, I have a board for my Compute Module 4, which I own, the PiTray(https://sourcekit.cc/#/) so to find something that works for my case was nearly impossible. I opened Fusion360, and since I started designing my own case for the PiTray, I choose to make some other variants based on the schematics of the other boards. As you can understand, I have not tested the variants, but tried to keep it as close as possible to the official designs for raspberry pi 4 and 5.

Also, despite the most usual way to compine top and bottom components, the clips, I choose to hold the case in place with screws and brass inserts. 
Important Note: Since the standoffs for the brass inserts are pretty thin you have to be very careful when inserting them. I used 2.5 with a diameter of 3.6 but I would strongly suggest to go with something smaller. Also, keep the temperature of the soldering iron at the minimum of your tool. I went with 180 celcious, since my iron could not handle something lower than that, but it was still high for the thin walls.

Mounting Bracket

The bracket uses clips to hold pretty hard on the aluminum skeleton of the Ender 3. I tried for it to be more stiff than loose so it can hold the case as stable as possible. The two pegs in the front of the bracket goes into the case and, having a small cavity, can keep it safe from sliding and falling of the bracket.

I tried to put it on and off many times, and seems that it holds still strong and without an issue. I designed it on my Ender 3 V2 Neo aluminum structure, but I believe that it can work on any printer with the same characteristics as Ender 3.

Supports

I didn't use any supports on my case parts and they came out pretty well and without an issue. On the other hand, I printed my bracket on vertical position, using supports for the clips and the standoffs, and a brim to keep it in place while printing. I choose this position so the clips would be the strongest part of the design.

So that's it. Every comment, correction, tip, trick and anything else are welcomed and appreciated as I said and before. I would try to improve the design based on your suggestions, so comments and makes are very important for me. 

Lastly, likes and reviews, give me a reason to keep this models lifecycle alive.
