Anycubic I3 Mega Hotend Cover V2

cults3d

This is the second version of my hotend cover for the Anycubic I3 Mega, featuring a primary change from the previous iteration - the area for the front fan has been reworked to accommodate a 20mm deep installation. This upgrade boasts improved airflow courtesy of the Noctua NF-A4x20 FLX 40mm fan, which is designed to deliver more airflow while minimizing noise levels. Installing the nuts within the pipe requires some dexterity and a bit of brute force, as the process can be quite challenging. The print time for the pipe came in at approximately 0:51h, with the chassis taking around 2:48h to complete. Filament usage was measured at 11g for the pipe and 37g for the chassis. Here's a breakdown of the required components: * 4x screw M3x30 (fan/front) * 2x screw M3x6 (chassis/rear) * 2x screw M3x10 (chassis/top) * 8x nut M3 However, there's an issue with this design: the NF-A4x20 fan is currently not functioning as intended. It only turns when connected to a 12V power source. In contrast, the NF-A4x10 fan continues to operate smoothly on the Anycubic without any issues - no blown drivers detected. The model appears to be a good fit, but there's an underlying problem with the electronics that needs to be addressed. The system should be able to function as expected, but for now, it falls short of delivering its intended performance.
