NOTE This is a remix of a fan part I got off thingiverse months ago, I can't seem to find it at this time (there's another remix that has a similar note as this). It was, according to the file I have saved, called 40-mm E3D Fan....
This fan has a valve built in to allow a small 1/8th turn to control fan flow. My MP Select Min refuses to listen to the fan, so I made this so that I could keep the vent closed on the first layer of some prints, then open in it up afterwards.
The print's still a WIP. Here are some notes and issues:
- I'm sure it's not the model, but my ABS version of this is fragile at the neck between the e3d clasps and the main body.
- Id print with supports EVERYWHERE, granted this will need some cleaning up with a stencil knife or similar.
- You'll wanna apply a tiny bit of forces as you clean up too get the valve to turn, but it should all go well, printed it twice.
You may not need 100% infill, but anytime i print parts for the hotend, I go 100% and would suggest it as well. Support is suggested everywhere on the model but know that this will need a small amount of fine clean up.
Carefully apply pressure to the inside valve to get it to snap free of the support, clean with stencil knife or similar.
