Proximity switch holder/fan combo

Proximity switch holder/fan combo

thingiverse

I wanted a fan to cool the extrusion when on bridges so I modified my earlier proximity switch holder design to incorporate the fan mount and director nozzle. Again it is optimized for a REX hot end. I used very coarse support for this to make cleaning out the funnel easier. I made it from PLA and have turned off the fan and printed ABS without any melting of the end of the nozzle. Hot end maximum temperature tried without the fan on is 245C.
