After some problems extruding ABS through my J Head MkIV nozzle I decided to install a fan for active cooling whilst printing.
As I needed an offset mount for anything smaller than 50mm for my X-carriage, I designed this mounting and guard.
Simple and minamalistic!
Print both parts.
Use a soldering iron to melt in your m3 nuts (makes for a tight fit!).
Mount to X-carriage.
