For years now people have been 3D printing their own versions of HAL 9000, usually as a computer case or a camera housing. Now, however, it’s a bit more analogue in this peephole cover that may be for you if you like to intimidate house guests.

Maker Jiří Masopust is the person behind this project, which is a thin plate which fits over an existing peephole and acts as a bit of decoration for fans of 2001: A Space Odyssey.

Masopust tells us that the HAL 9000 print was modelled in FreeCAD as he’s a fan of open source projects and Linux.

Creating the model in FreeCAD only took a few hours with the final result being a print that is separated into three parts: a base, the top fill and a grid which sits under the ominous red “eye”.

Speaking of that effect for the pictures on this page was achieved with a temporary LED so you have to be willing to blind any visitors if you want that accurate look. Most of the time it will be a dormant, clear glass at the centre here. That being said Masopust is working on another version which will incorporate a light source and a switch to make it more permanent.

Printing took just over an hour to complete with the assembled piece being ten centimetres long and four centimetres wide. Just two colours of filament are needed here – black and grey – as the HAL 9000 logo can be printed (with ink, on paper) and glued on to the plastic.

Finishing work is not needed here as the front facing parts are printed upside down for a smooth look but you may want to break out the sandpaper depending on your specific print.

You may want to break out some paint, however, as many peepholes come with a silver metal ring around the lens which doesn’t fit in. It’s suggested that the glass be covered with some tape so you can paint that ring the appropriate black.

Before that, however, grab the files for free over on Thingiverse.
