This is a 3d printable design which can house different electronic circuit boards. In its standard size it can house a 70mm x 100mm PCB.
Top and bottom halves of the boxes are identical. There is only one STL file for the box and it can be used both as the bottom or the top halve. There are many vents and holes to cool the interior electronics. There is also a simpler version without the holes & vents.
the two halves are fixed to each other by melting the tips of the 4 plastic pins in between them. You can also break away the pins and use screws. The knob design is also included as a 3d printable STL file.
The STL files are at the following pages.Pages: 1 2 3 4 5
