Update: DRAWSFramePi4 and DRAWSBasePi4 initial build for Pi4 B, DRAWStopPP and DRAWSTop, still fit.
This includes a thin layer of the hole for power cable in the frame, this can be carefully drilled out.
Update: DRAWStopPP - this top plate supports the installation of Anderson Powerpoles.
This is a very specific mod to support the nw-digital DRAWS Hat (Jun 2019).
Note position of the SMA.
The case is in 3 pieces. The base is mostly standard, I added a small cutout to see the power up and activity LED. I also added M3 threads for the outer screws and M2.5 threads for the inner screws and extended them all the way through. (The original design had M3 here that was useless).
The Frame section includes a hole above the Ethernet port. I use a simple M8 tap and then screw in a 2.1/5.5 power socket, that is soldered to the power cable. You could just pass the cable through here instead.
I have added some vertical slits to improve airflow, but may need more.
I currently use 35mm M3 screws to hold it all together.
P.S. The walls are very thin and I print very fast so you can see the lines, doesn't matter this is function over form, if you slice at .15 and run a bit slower it's smooth.
I tried to load the stl's the right way for printing.... I print the top upside down (on a textured surface) otherwise it doesn't matter. The Frame should be "upside down" so that the flat side of frame is down. The base should be printed right way up.
The new DRAWStopPP prints without support as long as bridging is working well.
May need to trim the holes for the 6 pin DIN
The 6 pin DIN hole can be subject to slight bridging, I found just putting the cable in and out a few times was enough.
The case needs to be eased around the sma and 6 pin DIN connectors, then should sit ok.
The Powerpoles fit snugly, although there is a 2.5mm hole to lock it in place with a grub screw or short (5-8 mm) M2.5, [M3 will fit if you try hard enough!]
