BIQU B1 cooling upgrade + BL touch

And the piece de resistance, a whole new head design.

Including :

• BL Touch support
• 4020 axial fan for heatsink
• 5015 radial fan for extruder

Cooling duct is directly taken from HeroMe Gen 5 on thingiverse.

You'll need :

• a few M3 brass inserts
• a few M3 screw
• your head (if possible)
• a bit of patience

Have fun,

And feel free to comment :-)

[edit] I added a custom Firmware for the support, with full instructions. Found in ZIP file !

Aslo, I advice gluing the BL touch support, as i had trouble calibrating it because it moved a bit ... Might not be necessary though.
