Our expedition vehicle based on a Mercedes-Benz Sprinter 4×4 leaves only a few options to ventilate properly from the factory.

Introduction Circular, uniform and bright illumination is an essential requirement in stereomicroscopy. Unfortunately, cheap ringlights are either not bright enough or too simple in design. Industrial illumination systems for stereomicroscopes (e.g. SCHOTT, or ZEISS), on the other hand, are ridiculously expensive. So it was up to me to build something of my own. I have … - Universal bottle washer for the sink

I was dissatisfied with the freely available coolers for my applications and so decided to design my own version. The most important feature for me was the use of a 60 mm axial fan to be able to guarantee a high volume flow and thus excellent cooling performance. This is crucial when using high-temperature filaments (e.g. nylon) and at high installation temperatures (e.g. ASA > 60 °C). Hotend cooling is required to restrict extrusion to the heater and nozzle. Without sufficient cooling, the heat will rise and cause clogging. I optimized the cooler for the MicroSwiss Hotend at my Creality Ender 3 Pro.
