Prometheus V2 40mm Cooling Fan Shroud - Adjustable Height- Version 2

thingiverse

!!Revision Update!! Ver2 Larger space between the two cooling tubes prevents them from touching the heat block when using a single nut on the hotend, thereby preventing melting. I have updated both the STL and SLDPRT files to reflect the correct version (Ver2). If you prefer an older version for any reason, please let me know. An adjustable height cooling fan shroud has been incorporated for use with the Prometheus V2. Although I have not extensively tested various heights settings, I am currently using it with 2 nuts under the heat block, one nut above and a 2 mm transition zone. While this configuration should work for all setups, I do not guarantee its efficacy. I am releasing the design to you now so that you can use or modify it as needed. As evident from the pictures and print quality, I have reached a point where I am willing to share my work with others. Printer Settings Tevo Tarantula Rafts: None Supports: Yes Resolution: 0.3 mm Infill: 20% Notes: Printed using Makergeeks ABS at 40 mm/s and a layer height of 0.3 mm, taking approximately 8 hours to complete. Lower layer heights (0.1 or 0.2 mm) printed at 20 mm/s would likely produce better results. A 27 overhang threshold is used with Slic3r, resulting in internal supports within the shroud that are somewhat difficult to clean. Manual support generation through S3D or incorporation into the design would be a more preferable approach. The bolt provided can be omitted; instead, you can tap a 5/16" hole and use a 5/16" bolt where the printed bolt is intended to go. If using the printed bolt, ensure that it has at least 50% infill for optimal strength.
