Raspberry PI 3 A+ Sleeve with 2020 rail mount.

thingiverse

Mounting a Raspberry Pi 3 A+ on a 2020 rail requires some careful planning and execution. To get started, I headed to Thingiverse where I found a remix of an existing design that caught my eye - https://www.thingiverse.com/thing:1050640. This design had all the features I needed plus a few extras. The first thing I noticed was that it had a window for the LED's on a 3 A+ which is perfect for adding some extra flair to your build. The rail mount is also designed to securely hold the Raspberry Pi in place, giving you peace of mind knowing it won't shift around while you're working on your project. If you're looking to create a back cover for your Raspberry Pi, be sure to check out the original design which can be found at Thingiverse as well. With these two parts combined, you'll have everything you need to build a sturdy and functional enclosure for your Raspberry Pi 3 A+.
