Summary

Description
This is a triangularly shaped cover for the Be Quiet! Pure Loop 3 LX all in one liquid cooler. The cover has been shaped in a way that it matches with the modern design of the AIO its holes can perfectly show off the RGB of the cooler. If you're the kind of person who does not appreciate RGB as much as some others do, then there is of course still the possibility to turn off the RGB and the cover will still look good and work perfectly. There's different ways to print it and there's no assembly required. You can make it in one solid colour like in the first three photos, or you could print it with multiple colours like in the last two pictures. I recommend printing it with some supports which you could easily take off afterwards. If your printer likes to leave traces of the supports on the print, this wouldn't matter as they would be on the underside which isn't visible when the cover gets mounted onto the cooler. By the way, if you're wondering, the renders were made with Fusion 360.
