Pine64 A64 / A64+ case

This case for the Pine64 does not need screws, it easily snaps together after printing.

Printing

The attached .3mf file has the parts ordered so everything prints in one operation. With my 0.8mm nozzle it took a bit over 3h to print. There is a version for printing with an 0.4mm nozzle, but I haven't tested it. Let me know if you encounter problems.

Everything except the shell can be printed laying flat on the bed, but the shell needs to be printed upright and without some extra help won't stick to the bed. The .3mf file has some small helper disks attached to the insides of the corners, which was sufficient for PLA on the smooth bed. I imaging printing with a generous brim would also work, but the disks are very easy to remove (as shown in the photos, cutting the corners of disks and then breaking them off leaves very little to clean up with a file or deburring tool).

I printed the case in PLA, but I don't really see why PETG shouldn't work, it might be more trouble because of the overhangs on the underside of the shell, but nothing depends on those dimensions.

If you want the version of the case that does not include a hole for an external Wifi antenna replace the FaceplateA with the FaceplateAnowifi, both .3mf files include the version with that hole. (Because that's what I needed, sorry.)

Assembly

Sliding the Baseplate into the shell took a bit of force at first (and I helped by cleaning up some stringing with a small file, shown in a photo), but it's supposed to be a nice tight fit to keep everything together. The frontplates snap into place, but may need some convincing; I start by putting one of the short sides in and then use some force to get the other side to snap into place. 
I started with the side that has round holes for audio and Wifi antenna, slid in the pine64 and then snapped in the other faceplate that covers the HDMI, Ethernet and Micro-USB connectors.

Model - Modifications

Everything was modeled in FreeCAD, I didn't make it parametric because the  only things that might need modification are the Frontplate layout (which needs to be changed manually, anyway, by adding holes) and the height of the box, which should be easy enough in the sketch for the first Pad of the Shell body. 

If you need modifications but don't know FreeCAD, just ask me, I might add them.
