What do you do if you have access to a 3D printer and also are a reefer? You build some cool gadgets like this 3D printed protein skimmer designed to fit a plastic two liter bottle. These images were shared on Imgur recently by madscientistcoral with just a little background information. According to their captions, the design was created Solidworks, a 3D CAD program, and printed them in PLA to test how well everything fit together. From the images uploaded, it looks like it all works. If you are interested in printing one yourself, they plan on uploading the files to Thingiverse for download so that you can print your own.
