Anycubic Vyper Mainboard Fan Cover 120x120x25

thingiverse

Another attempt for a fan cover for the Vyper mainboard. I had a 120mm fan lying around which has a similar amount of air throughput as the original 24v fan (> 79 m³/h). The four mounting holes are for a XL4015 step down converter, which, though way too overpowered, I also had lying around. The screws used for the XL4015 have some very thin heads, design is tailored for them. The first version is 203mm in height, which was a little too large to nicely fit the additional PSU baseplate cover. I probably won't use that additional cover so does not bother me, but if anybody wants to, I included another version which is 200mm height. The fan will stick out of the bottom, so simple extensions to the feet are included. Idea is to remove the rubber feets, glue the extensions in place and then glue the rubber feets to the extensions (not yet tested). Images show the first 203mm high version. Wiring should be visible in the images too. Be sure to set your step down potentiometer to output 12V. Wiring input voltage directly to 24V PSU and output ground to the original 24V mainboard fan connector is necessary to a) not fry your mainboard transistors and b) allow mainboard to start/stop the fan. Wire coloring in the pictures is red/orange: positive, black/white: negative. So wiring goes: - +24V-PSU -> +XL4015-Input - -24V-PSU -> -XL4015-Input - +XL4015-Output -> +Fan - -Fan -> -24V-Mainboard Be careful to not damage anything. I won't take any responsibilities if you do. You have been warned ;-) I also included FreeCAD files for easier customization.
