Side mounted fan duct for a rostock effector.

My custom water-cooled thermal break cold part really performs, thanks to the innovative design that I came up with myself. Since swapping out my old hot end for a robust metal replacement, my print piece fan cooling has gotten significantly better, especially with the addition of a side fan. Be sure to allow at least 40mm of clearance between your effector's underside and the base it sits on to give the system room to breathe - this will ensure that heat dissipates properly from your print. One more thing I should mention: using swivel joints for my effector and carriages is a game-changer, as it keeps them securely attached via external mounts; however, standard universal joints won't work in conjunction with these mounts. When working with sensitive materials like nylon or PET-G, be sure to turn off your fan before starting the print job. Now, onto the installation process: To increase bed clearance from the first iteration of my design, I designed Version 2, which provided even more space. On my RepRap, I used a 15-perimeter brim setting in conjunction with a layer height of 2mm and a travel speed of 50mm/sec. Other print parameters included 1.05mm wall thickness, a nozzle diameter of 0.35mm, a top and bottom layer height of 1mm, and a fill density of 30%. At the time, my heated bed was set to an impressive 75 degrees Celsius. During the process, I utilized Pritt's glue stick spread out in a crosshatch pattern along with a damp paper towel applied on top of the glass build plate. Small amounts of exterior PVA glue were then added at each corner where the brim and nozzle touched down; these spots were roughly 2 layers above the actual print surface. As you might have guessed, I encountered some hiccups when attempting to get my nylon prints right – namely excessive lift-off on the edges due to poor adherence to the bed. With that in mind, my printer was pushed up to 260 degrees Celsius for maximum thermal head performance; but honestly, my actual temperature may be slightly higher than my readouts indicate due to miscalibrated settings.
