Qidi Plus 4 Voronoi Toolhead Shrouds

Overview

A voronoi style toolhead cover with an optional 4010 fan version. Replacing the stock fan with a 4010 drastically reduces noise. Two 4x1.5mm magnets are required to fasten the cover to the toolhead. Magnets are a very tight press fit, make the hole slightly larger using a drill bit if needed. I squeeze them in with a pair of pliers. I originally got the idea for the 4010 fans from Kameo. If you do not wish to use the 4010 option, I do suggest you use this Hotend Air duct to reduce heat creep as both of these options work very well. I have also uploaded a blank stock Qidi toolhead cover step file for you to design your own toolhead cover, and also a step file I left the vents on. Enjoy!

4010 Instructions

This modification is done at your own risk. Installing a 4010 is extremely easy on the plus 4. I have tested many 4010 fans for fitment and they all fit, even a Noctua a4x10(although a tight fit). Fans should be 24V, but a 12v could be used with a small buck converter hidden in the cover. Start by removing your shroud, you will be removing the screws circled in the image to remove the stock fan and its mounting plate.

You will also need to remove the back cover to access the fan header. You do this by putting your fingers between the part cooling fan and sliding the cover up as shown in the picture below:

Once the cover is off you will be presented with your fan header and an additional unpopulated header. I have not tested the unpopulated header's functionality, but believe it to be an additional 24v fan header.

Simply unplug the stock fan and plug your new fan in the already existing port. To run your wire you will need to remove a wire shroud on the top as in the picture. It slides out being retained by the central part of the toolhead cover.

The stock fan is a 2 pin 24V fan so I do recommend getting a 2 pin 24v as well, but some of you may find yourselves with a 3 or 4 pin PWM fan. In order to use these you will need to get a pinout of the fan you purchased, if they have not provided you an adapter. I have provided the pinout for a Noctua A4x10 below, even though you should get an adapter with it. You will need to use the +24v and the ground wire to power it. All other wires should be trimmed back ad secured as to not cause a short. In the instance of using a 12V, a small buck converter must be installed within the shroud.

Printing

The covers are designed to be printed face down, with the only supports being recommended are the back of the fan hole. See image below.

For this reason I recommend manual tree supports and just use support painting in the area in green. Auto supports work as well, but make for a messy cleanup. This being said, some materials are better with overhangs than others, please support accordingly. 

Nozzle: .4

Filament: PETG/ASA/ABS/PA

Layer Height: .2

Infill: 100% or 999 walls

Supports: Yes
