bpi4 case RV1.7.3mf (388.5 KB)
I added some more to the tolerances on stuff to make it an easier fit.

Actually, looking at the original sized pics that you had posted there, there’s something wrong with the mounting of the board or the print.
The SFP cages should be flush with the face, but in the pic it looks like yours are back 1~1.5mm. (PCB setback is 6.875mm)
The RJ45 block should be almost flush, like ~0.15mm at most away from the face (PCB setback is at ~6.74 mm)
The DC jack will also be the same as the RJ45 block, either flush or just slightly recessed. (if I print using a 0.4 nozzle, it’s flush, a 0.6, it’s slightly recessed)
On the inside, the board should be flush against the inside face.
If you don’t have the SFP cages flush with the front, then you won’t actually be able to insert any modules into them because the case will keep them from being able to insert all the way due to the module locks on the bottom. I’m using DAC and 10Gbit modules in mine and they fully insert correctly, locking into place.
Thanks! I just ordered a bpi-r4, barebones. I have to wait a few weeks for shipping. In the meantime, I’m keen to print a case for it. Just leaving a comment here so you know there’s still interest from the masses.
Really nice.
Would you have the files in a format that would be compatible with easy editing in FreeCad ?
I’ve a 5G modem on the top slot and need 4 holes for the antennas above the PCB.
When the wifi7 card arrives. I don’t know, but might it need a fan on the bottom side of the board also, to keep all the wifi chips cool.
AsiaRFs’ Paul Lai just responded to my email where he says, “Kindly be noted the single mini PCIe or M.2 module will be available in next month.” [emphasis added], referring to the Wifi 7 board for the Banana Pi BPI-R4.
This sounds confusing to me. The Wifi 7 board for the BPI-R4 is developed and manufactured by Sinovoip and not by AsiaRF.
Are you referring to the one of those modules AW7916-NPD Wi-Fi 6E AX3000 Mini PCIe Module - AsiaRF here?
I found it a little confusing too as English is their second language. I’ll just post the whole conversation.
I was going to order “Wi-Fi 7 Module AW7256-P01 Mini PCle MediaTek MT7996AV” from AsiaRF which was available on their website a couple days ago. It has since been removed.
Me: “I am looking to buy a wifi 7 module (Wi-Fi 7 Module AW7256-P01 Mini PCle MediaTek MT7996AV) for a Banana Pi-R4 for evaluation and research purposes, but when I added the item to my cart and did checkout, the shipping was calculated to be $138USD. That’s a little crazy. I was wondering if you could give me a better quote for shipping to this address: [Removed]”
Paul Lai: “Dear Radford, Excuse us, we are sorry some issues in our web system. We will be available for customer ordering in next week for full board system. Please order later for full system. We don’t sell module only now. Kindly be noted the single mini PCIe or M.2 module will be available in next month.”
(This should probably be in its own thread anyway. I originally just meant to quickly update following jcdutton’s last comment)
Hello, on the box where the switches for reading from the nand or sd card are, can you make a hole to move the position of the levers without taking the cover apart.
Hi all! I understand that the problem of all engineers and electronics specialists (including me) is the case. I would like to ask: maybe together we can draw something other than a parallelepiped? Something more modern and different looking? At the moment, I asked a friend to draw a body similar or the same as that of the TPlink Be900, but he is still on vacation. Therefore, for now I’ll start sketching, taking into account the fact that the case is supposed to have a removable fan and a 2.5-inch hard drive for files. So, if you are interested, I will post the result here.
I have remixed this design to allow for a screwless composition (a 6-part modular design + 4 feet) and 3 (wider hole) antennas, the ones sold by AsiaRF in a pack with AW7916. It is meant to mount the board upside-down.
I’m not planning to develop this design any further, just wanted to share it (alongside a source Blender file).

Anybody skilled with openscad could consider contributing to GitHub - hominoids/SBC_Model_Framework: A framework for the generation of SBC and micro-controller models ? It might make adapting over the boards generations quicker. 
Hi! I was trying to modify the case myself and started with recreating a simplified model of R4 using the CAD files here and dxf drawings from wiki, however the mounting hole spacing is off by 0.5 mm and I have issues getting ports to line up, is this something by design for something effect during 3D printing?
Would it be possible to get the latest version of this in an STL or other format that works well in FreeCad or OpenSCAD? Can’t seem to get the 3mf file to import well to modify.
Is there a way to make this case rackmountable for a 19 inch by 1U rack?
I’m sorry but I cannot relate. Public projects for things like RPi work - this deviates a lot from BPi I have.
I created a v2 ceiling access point case. I converted two bpi-r4 to use poe+ and mounted both of them on the ceiling in my home. They’ve been working well with a 120mm fan. I’m seeing idle temps of 33c and peaks of 59c.

May I ask which antennas you used? I plan something similar!
