Description
A replacement mainboard cover for the Qidi Plus4 that allows for the use of an 80x25mm fan
This is a variant of my other honeycomb design posted on Thingiverse
This variant positions the fan more centrally over the hottest parts of the mainboard, being the stepper drivers, the Rockchip CPU, and the STM32 MCU.
Included is a printable ducting which may be attached to the fan using M4x12mm machine screws which screw directly into the ducting.
A vaned fan cover is also included to protect the fan inlet from debris.
Best printed with a 0.2mm layer height. No supports necessary.
A 0.15mm elephant foot compensation over 3 layers is recommended for the honeycomb cover plate.
Any material can be used, but I would recommend filaments that can withstand at least 60C before softening for best long term durability.
