This is a remix of the Pruisa i3 MK3 extruder mount for the BLV linear rail mod with a E3D V6 bowden setup.
I wanted to have a minimal and stiff mount which suits a 40 mm fan and the common BL-Touch (Smart).
For the belt holder I would suggest using this one : https://www.thingiverse.com/thing:2746489
Update 3 : 01.02.19
updated the "Base" as pointed out by Lanktus
-> added a through hole to the other side pointing away from the leadscrew
-> added a small vertical path for wires
-> minimal Endstop included for attaching directly to the mgn rail for potential collision problems
Update 2 : 24.06.18
Update 1 : 07.04.18
-> Inserted the missing holes for the stock belt holder
Resolution and Infill is up to you - I used fairly high infill percentage to make it reliable and stiff
Nozzle to probe offset is in the images.
Assembly and what I used:
11x M3 - nuts
2x M3x30 - putting the 2 parts (base and cover) together
2x M3x23 - mounting the 5050Fan
4x M3x18 - 40 mm Fan + Cover (use whatever you'd like to)
3x M3x10 - Nozzle-Fan and BL-Touch
- 4x M3 screws to mount the base to the linear carrier -> see BLV
