This is a BIQU H2 mount for the base Ender 3/3 Pro and the Ender 3 V2.
It comes in 2 variants, depending if you prefer to mount one or two 5015 fans.
Key features
Both single and dual mount have been printed, installed and tested ;) I posted a make if you want to see in for real.

BOM
For this build, you'll need a couple of M3 and M2 screws and nuts :
Support are only required for some small areas. You can probably print without any and get a functional print, but i'd advise to use paint-on-supports for best results.
All pieces are designed to be printed flat on their flattest side, including the ducts.
You can print with 0.4mm or 0.6mm toolhead, preferably in PETG, but PLA works fine as well.
1 - Try all screw holes before building. Some are designed to be tight in order to keep in place the screw.
2 - Build the carriage fan support on the carriage using two M2 6mm.
3 - Install the two M3 8mm screw that will hold the whole support on the ender's carriage (the one in the middle of the fan support, and the other one slighty above.
4 - Install the BIQU H2, without its fan, using the M3 8mm from the back of the support. Use the wide gap in the support to arrange and hide the heater cardrige and thermistor cable
5 - Install the mount on the ender's carriage and fasten the 2 M3 8mm from step 3. Use the gutter on the mount to organise the BIQU fan wire.
6 - Mount the LED strip using 2 M3 6mm screws
7 - Install the BIQU H2 fan using 2 M3 20mm screws
8 - Install the fan mount loosely using the 4 M3 6mm screws. Don't tight them much for now.
9 - Install the fan duct(s) using the two M2 8mm screws.
10 - Level your toolhead, and leave 3mm of clearance between the noozle and the duct(s). You can use a M4 Hex key to help you with that
11 - Install the fan(s) and secure it/them using 2 or 4 M3 20mm screws and nuts. I suggest to add a touch of glue on the nuts to keep them in place in the mount. For the double 5015 version, use the gutter on the mount to hide the left fan wire.
12 - Mount the BL Touch on it support using the M2.5 screws provided with the sensor
13 - Mount the BL Touch support using the M2 16mm and M2 12mm screws
14 - Mount the ADXL345 using 2 M3 6mm screws
15 - Mount the cable support on top using the last M3 6mm screw
Build is now complete ! Wire everything correctly on your board, double-check your wirings, reconfigure your extruder e-step and current voltage in your firmware, make some test print and you should be good to go !
