Biqu B1 - Biqu H2 V2S dragchain mount

###This is a Work in Progress###

I dont like the mount that Bigtreetech suggests, thanks to Zaurko & Bart Geldof for the inspiration

This mount is the least destructive way to install the H2 Extruder to the B1. You can use the same PCB daughterboard and USB-C cable, same X end switch and same 4010 fans.

I added perforations for 10x10mm drag chains. But I would suggest something slightly bigger to help with cabling. So these might change.

In this first version, expect the fan duct to heat, warp and smell a little since it touches the silicon on the heating block. I expect to change the ducts in the future

I like to park my printer a little outside of the hot bed so the filament has space to ooze while heating and I have enough space to clean the nozzle

Printed in PETG no supports required if you have the correct bridge settings

###You will require the next material:###
* 2 meters of Red and Black cable
* x4 female 2pin JST connectors
* JST connector crimper
* x2 M3*12 screws
* x11 M3*8 screws
* x2 M4*8 screws
* x1 M5*12 screw
* 45cm 10x10 nylon drag chain
* 2mm heatshrink
* 6mm heatshrink
* Reuse fan M2 screws to mount fans to new duct

###Necessary modifications:###
* Shorten the hotend fan
* Shorten the heat cartridge cables and add JST connector
* Add cable to your existing 410 part cooling fan cables and add JST connector (You can also use other fan ducts from Zauruko for different size fans)
* Extend the preinstalled extruder motor cable (Note that if you go color by color the extruder will be reversed, that can be fixed by swapping the polarity, using negative number of steps or changing the firmware)
* BL touch offset - X=40.95 Y=-26.3
* define NOZZLE_TO_PROBE_OFFSET { 40.95, -26.3, -1.5 }
