This is a mount to put the Biqu H2 extruder on the Creality CR10-S Pro v2. I do not know if this will fit the V1 printer but suspect that it should.
Important: Replace the two m5 x 8 cap screws that attach the x-axis 2020 rail on the right side with button head screws to allow clearance for the backplate as I did not want to make the extrusion any thicker than necessary.
Insert two m3 hex nuts into the back of the mount for the BlTouch bracket.
Use m3 x 8mm socket head cap screws inserted through the back of the mount to attach the extruder.
Attach the BlTouch bracket from the front of the mount using m3 x 8mm screws. I used button head screws.
Attach the mount to the backplate using the top two screws for the x-axis rollers.
Attach the BlTouch to the bracket. I reused the old ones that held it to the stock aluminum bracket.
BlTouch offsets: X -43.4, Y -2.3
This was done in PLA except for the duct which was done with PETG.
I used the parts fan mount from fhogphil https://www.thingiverse.com/thing:4764077 The fan duct came from Hangtight https://www.thingiverse.com/thing:4042492
