This is a compact enclosure I designed for my simple four-LED binary clock. The case is designed to hold a small PCB along with two pushbuttons. The cutouts in the front panel allow these buttons to pressed through the plastic-covered printed paper artwork. An example of a suitable front panel is shown in the pictures below. I've uploaded this object here because it might have wider use than just my original binary clock application. The enclosure includes a hole for a power cable. I've also attached the DesignSpark Mechanical files for those wanting to adapt the design for their own requirements. The electronics are described over on my website at www.zl2pd.com if anyone is remotely interested.I printed this using PLA filament on my Printrbot Simple Metal using 0.2mm layers and a shell thickness of 0.8mm. I set fill density to 15%. I don't have a heated bed so I printed it base downwards, just as it sits on the table in use, directly on printer's tape without any additional support.
