GEEETech i3B/C (METAL version): Single Extruder FAN & LED (V2)

thingiverse

Hi, now GEEETech proposes the Acrylic Prusa i3 Pro series, B for single extruder and C for dual extruder, with metallic parts instead of original printer ones. I've ordered the upgrade kit immediately to improve the stability and quality of my already-not-so-bad printer. Unfortunately, the customization I designed for the plastic version cannot be used on the metal one, so I'm designing a completely new customization, starting from all lessons learned from my original design! One key lesson was to decouple all contacts to enable easy mounting, maintenance, and upgrade. Here's the Mono Extruder FAN & LED component of my new customization in its second iteration version. This design includes space for ties to keep cables in position, as seen in my photos. I've added some optional components: 1) For FAN Ducts, you can choose from closed or open versions - I prefer closed ones, but many people like the open version. 2) For ABL sensors, you'll find support for both rectangular IR sensors like mine and PiBot's one. 3) For rectangular ABL sensors, there's also a 4D design to print flat. As usual in my designs, everything is split into easy-to-print components with simple mounting after printing. From V1 to V2, this version includes a duct to collect MK8 fans from the cool zone for better cooling and preventing clogs - especially when using filaments requiring higher temperatures, which can cause problems with the 38mm barrel. P.S.: After installing this customization, it's a good idea to re-execute the PID Autotest. I did two tests: one with the fan off and one with the fan on, both significantly different from previous tests conducted just hours before!
