Adjustable Vent for Delonghi Pinguino Compact Portable Air Conditioner PACES72CLASSIC

This is a press on fit directional vent for the Delonghi Pinguino Compact Portable Air Conditioner (PACES72CLASSIC)

I'd advise before printing this whole project to first print the test piece and ensure it can be attached to the machine/pressed into the standard vent.
The test piece should fit quite firmly, if you are not comfortable pressing the piece into the original vent or are concerned you will break the plastics on your machine DO NOT PROCEED.

You will additionally need M3 CounterSunk bolts to complete:
1 x M3 16mm CS
7 x M3 12mm CS (you can possibly use 10mm)

Instructions:

1)Print Test piece, check that it can be pressed into the vent on your machine. I printed on a Bambu A1, 0.4mm nozzle stock settings, and eSun PLA+, my printers dimensional accuracy may vary compared to yours so it's better for you to test if this will work first with this small(ish) amount of filament. There may be a small amount of flex in the test print to fit.

2)If the above fits, Print the Main Chassis, then the Vent Fascia flat side down (default orientation). 
For both of these pieces use tree support just on the overhang that holds in the adjuster rail, and for the large oval(ish) hole on the fascia panel.

3)Print 8x vent blades flat side down (default orientation). These are thin and intended to flex to be put into the chassis, don't print in anything exotic/reinforced (I used pla+). The round (rotator) part of the fin has an intentional flat spot so they're easier to print, they'll still rotate fine in the main chassis holes.

4)Print adjuster rail, adjuster knob and installation helper, no support needed.

5)Put the vent blades into the main Chassis, they will need to be flexed into place, please see photos for correct orientation of the vent fins.

6)Use the installation helper piece as shown to align the fan blades straight upwards in the chassis.

7)Install the adjuster rail in the slot at the top of the frame, make sure that it aligns with the vent fins (this is what will move the fins left and right)

8)Slightly difficult part - being careful not to knock the adjuster rail or installation helper out, fit the Fascia piece. You may need to place it on the frame curved side/bottom edge first to clear over the vent fins, then click it down over the top of the frame so that it holds in the adjuster rail (all while not letting it fall apart!) Apologies if this part is difficult and not very straight forward, I don't think there is an easier way to design something like this that moves linked in unison. Please look at the pictures carefully if you are struggling/confused.

9)Screw the fascia piece into place using the 7 x 12mm M3 screws, then remove the installation helper if you haven't already.

10)Use pliers to screw the 16mm screw into the adjuster knob as far as it will go. Then gently screw this into the small screw hole in the adjuster rail, DO NOT OVERTIGHTEN, it only needs to screw in about 2mm otherwise it may strip the hole/bind the mechanism. 

I was unfortunately way too far into the design/mentally over the project to make the attachment of the adjuster knob any sturdier. While you don't need to treat it with kid gloves, still advisable to treat it gently. It's potentially a design flaw if you have people/children in the house who treat things roughly, and could be a choking hazard for the later if broken off. I'd advise to somehow glue this into place or modify the design if you have children (ask nicely and I may share a link to my Tinkercad workings), or just omit the adjuster knob and move the fins by hand.

11)Press the unit into your Delonghi's vent and enjoy cool air in your direction!
