Adventurer 5M venting kit (for the non-Pro version). Easily vent to a 1.5" hose.

Three parts to easily vent the base model Adventurer 5M with simple diy parts.  

The general design here is that most enclosures are leaky, so it's good to ‘vacuum’ the chamber, making all the air leaks flow inward (and not into the room) - then we only have one exhaust flow, through an added fan, to your exhaust pipe.

To do this, we cap the recirc vent (it's useless in the non-pro model).  This makes the top vent the incoming air source, so air must cycle from top to bottom.  Then we discharge air through the bottom vent: a sealed path through an added 4020 fan, through the Internal Duct, through the External Adapter, and out to your hose.

This version is tuned to fit a Home Depot 1.5" drain hose, which are cheap to get, and wont melt with printer temps.

This design needs you to drill one hole in the back panel.  It's in a safe spot to do it, and the part guides you where to drill.  It's very easy.

This design expects a 4020 fan installed on the lower left vent.  How you power it is up to you.

• You will need a 4020 fan and simple screws to mount it (get a 24v one).  
• You will need four 6mm x 3mm magnets, which hold the Internal Duct in place.
• You will need a drill for just one hole, and any screw+nut combo to secure it.
• Print the three parts.

Install Instructions: Have all parts in hand before you begin, including the Recirc Cap, the Internal Duct, and the External Adapter.

1. power down, unplug, and remove the filament spool from the printer.
2. take the back panel off with the 6 screws.
3. look at the upper left, left of the mobo fan, there is a square vent.  Snap the Recirc Cap onto this vent, it is a snug fit.
4. look at the bottom left, there is an obvious spot for the 4020 fan.  Install it with the screws it came with.  Powering it is up to you.
5. Push the magnets into the Internal Duct's holes, all the way (there should be a gap in each hole).
6. Place the Internal Duct on the fan - the magnets will hold to the screws.
7. Place the rear panel back on, but only install the top two screws.
8. Place the External Adapter over the bottom left vent, and install the two case screws it overlaps.  
9. Use a pen/marker, and draw through the External Adapter 3rd hole onto the case, marking where the hole is.
10. Remove the External Adapter, and remove the rear panel off the printer.
11. Go drill the hole where you marked it on the rear panel.  Be sure your screw will fit through the External Adapter and the hole.
12. BEFORE you reinstall the rear panel, install the External Adapter 3rd hole screw onto the loose rear panel.  This lets you tighten whatever nut you have on the screw.
13. Now with the rear panel + External Adapter together, reinstall the back panel with all 6 screws.

Hint for powering your 4020 fan: there are 2 free screw terminals for +24v and Ground on the power supply.  The guard on those terminals flips up with just your fingers:  you can easily tap into power this way.
