Orange Pi 4 LTS Case

Couldn't find RPi4B in stock anywhere, so got an OrangePi 4 LTS instead. As it turned out, Orange Pi 4 LTS has a slightly different layout than the original OrangePi 4, including the reset and recover buttons being located in a different area.

This case was designed using an Orange Pi 4 (non-LTS) PCB (from GrabCAD) as a reference starting point and the rest of measurements were done with a caliper. I created openings for MicroSD slot, reset and recover buttons and all the “main” ports. I didn't add explicit access to GPIO or webcam and LCD ports.

The case should be able to snap together and it's snug-enough to prevent PCB from sliding around even without screws. Regardless, I would recommend securing the 2 half together using 4x M3 8mm or 10mm screws. 

If you want to use the antenna support or simply have the antenna outside of the case, simply pop it through one of the vent holes. The antenna support should snap anywhere in the top half's honeycomb vents.

I printed with PETG (initial prototypes using PLA), 0.2mm layer height, 20% infill, 6 walls for top and bottom pieces, 3 for antenna support. If you're using Cura, check how it slices the first layer of the honeycomb vents for top half, it has a tendency of making a mess of a few inner walls.

Created case v2 that has symmetrical offset for side walls. Case v1 (the one I printed for myself) had one side closer to the PCB than another, due to physical port placement on the PCB and I wanted easy port access. For case v2, I added an inset to make up for the lost 1mm and try to keep port as easily-accessible as in v1. I haven't printed v2 myself, so please let me know if there are issues with it.
If you're going to print v1, check that the “stands” of the top half align with the bottom half before inserting the PCB. Also for v1, you might want to insert the PCB with side that the HDMI port first.

(Also updated the antenna mount to make it smaller)
