This is just a small project to make some simple Raspberry Pi cases

Step 1: Cutting Acrylic/ Wood Pieces

Basically I used a penknife to score the acrylic and snap them into shape. However, most of the acrylic scraps were in shape already, so little trimming was needed

For the wood, I just used a penknife to cut some very soft but thick wood (From Daiso)

Step 2: Bending the Acrylic Pieces

As for bending the acrylic pieces, I placed a 60W soldering iron touching the bend to heat up the bend at the acrylic. When it is heated long enough (about < 10s), I bent the acrylic at 90 degrees with the help of the table end or a wooden block.

Step 3: Gluing It All Together

Just use some simple Hot glue to hold the acrylic and wood pieces together, where the acrylic are at the sides, and another piece of acrylic or wood is used as the bottom. The top cover is just another clear piece of plastic/acrylic

Step 4: Portable Raspberry Pi Setup in an A4 File

For this, just get a screen (7 inch one here), Raspberry Pi (a 3B+ used here), Power Banks (2 used here, for the Pi and Screen separately), connect them together with wires, and put all of them together in an A4 File. I used an A4 box file here, but any file with a suitable thickness would work. You can organise the components inside whatever way you want, making dividers out of cardboard (or corrugated plastic like in here) to seperate the components. Moreover, the empty space could be used to store some excess wires and cables just in case. (Like a mouse)

As for the way I organised, I firstly made acrylic cases for the 7 inch screen (and touchscreen, both which I done more than 2 years ago, but the design is similar to GreatScott's Mini monitor https://www.instructables.com/id/DIY-Portable-Mini-Monitor/ ) from eBay and the Raspberry Pi, before putting them into the file. This allows it to be modular, as you can easily remove the parts whenever you want
