Ngàm gắn rack Raspberry Pi Model B (v1)

Got a first generation Raspberry Pi Model B and rack mount it? Here you go!

• This model is for left rack mounting. You can't mirror it in your slicer because the mounting holes are not symmetrical. 
• Printing is straight forward- the only area where supports are needed are the holes for the rack mount bolts.
• Use M3 bolts to screw the Raspberry Pi to the mount. Any short length should be fine. The bolts may need some oomph to bite into the material.
• I would recommend printing in PETG, but PLA should be fine.

Development

I'm a terrible 3D modeler, but I can slice things up easily enough in TinkerCAD. This one took some work!

The part where I needed to get the holes lined up juuuust right was the hard part. In the end, I went through 15 iterations to get those lined up correctly.

Iteration can take a long while, but there are many times when your slicer's features can be in your favor. To save on used filament, I used the cut tool in my slicer to print a 1mm sliver of the mount to test. On my Mk4S, the iterative print would only take about 30 min before finishing, so that was a huge time saver.

In the end, I got a product that works perfectly, and my first generation Raspberry Pi is mounted underneath a Raspberry Pi 4. 

I think it came out well. :)
