Pi4 case for Ender3

This is a remix of Raspberry Pi carter for Ender 3 Pro by dbozec all credit goes to this creator.

Update: For some reason, the model viewer on Thingiverse is only making the V2 model visible twice instead of the two individual files. I have checked everything and re-downloaded the files from the site and confirmed after loading both into the slicer that both individual files are present. I'm not sure why the page is doing this.

The modifications I have made are as follows. First, I didn't realize this case was for a Pi3 until I tried to put my Pi4 into it. So I remodeled the holes to match the external port layout of the Pi4.

While I was at it, I decided to remove the vent holes from the side to improve print time and surface quality of the printed part. There is also a gap of a few millimeters all the way around where the top of the case meets the metal plate that holds the display on the Ender3 so it still has ample ventilation.

Last, I removed a tapered portion at the top back of the case because it obstructs the piezo speaker on the back of my display. Since this last part might not be an issue depending on what display you have, I have included models both before and after I removed this portion. Model V2 is the removed taper version.

The fan cover in my second picture is the 40mm Fan Cover by cdl1701, here is the direct link to that thing: https://www.thingiverse.com/thing:1341005

Not pictured but super helpful to me on this build were the V-Slot Cable Clips by pekcitron. These are simple and fast to print and were great for making sure the additional cables on my Klipper build stayed in place and did not obstruct any moving parts of the machine. Definitely worth checking out. Direct link here: https://www.thingiverse.com/thing:2676595

Some notes on assembly: I used two M2 x 4 x 3.5 brass inserts in the two mounting holes closest to the front (Farthest from the fan opening) to mount my Raspberry Pi and two M2 x 4mm screws and washers. The Raspberry Pi fits snugly inside this case by design and so getting it in place must be done carefully. Once it is in place, it can be fairly difficult to get back out. The two screws at the micro SD card end of the board are more than enough to ensure the board can't shift around when you plug in cables.

I have not installed a power converter in my case and am currently just using the type-C power supply the board came with. If I end up switching to a power converter or working out some additional bits to go with this I will revisit my listing and add whatever might be applicable.
