Magnetic Ventilation system v17 [for Resin Printers] WIP

First and foremost, 

Thank you OnceinaSixSide!!! what a fantastic Idea!

So i planed on just making it so I could use my magnets.. I have 8x3mm on hand… but I ended up redrawing it. it is also drawn to utilize m3 button head screws.

and added a twist lock… 
Currently untested, I will double check the measurements when I have the exhaust hose, and I plan printing these and using them (for my resin printer setup). 
I will let you know if they work :D (and even what changes needed to be made).

Time for some changes:
 

1.) updated dimensional accuracy. (actually four inches now) 
2.) added an inline fan coupler that works with a 92mm fan (for reference)
3.) added a second magnetic base “Magnetic-Base--WallVent” -for those that want to have it around the outside of their external vent. so the hose is easily removable from both sides.

I printed some of the parts (PETG). see photos. 

they fit perfectly on the fan and the pipe. 
I used 8x m4 x 12 mm socket  cap screws with a nut and a washer to put it all together. 

works well!

Finally gotten around to actually using these for venting my setup. 
going to make it less ad-hoc and more of a permanent solution.

so i needed to update the files a little bit. they were not perfect…
also wanted a way to filter incoming air, so I've added that solution. 
I'm pretty stoked, I think it will work well.

Added pics! 
got it plumbed in. (finally)
added a one way valve to cut back on back draft. 
recycled the pet plastic sheet that comes on a new laptop keyboard (cut to size for filter paper).
 

I think this setup is going to work very well indeed!

if you want more pics for a better understating of what I've got going on, lemme know. 
otherwise…

Enjoy!!!1

updated magnet size (8x3mm)
added twist lock for extra security (also now you don't need magnets - they are nice)
added filter cover for incoming air (has 3~4 parts)
strengthened and refined all parts for FDM
