Notes: The vent body does not rotate inside the AC vent opening as it uses the size of the print to push itself into the AC Vent hole.
Print Setting Instructions/Tips:
Use PETG or ABS or ASA or stronger material with better heat resistance.
Print the Flaps A and B solid at 100% infill.
Print the Vent Body at 15-20% infill, depending on personal strength preferences. I did 15% and it seems sturdy enough.
Hinge filament holes are modeled 1.92mm diameter. Depending on your printer's tolerances these are still quite tight sometimes and may require a little extra force/effort to slide filament into the holes. I use the flat edge of a pair of flush cutters/pliers to push the pieces of filament into the holes.
As I will not be moving these much, I did not do this step but if you want a more secure/permanent fit for all the pieces, the original author recommends: “Use pieces of 1.75mm filaments as shafts for hinges. Insert them in place, leave 1-2mm poking out, and use a heated piece of metal to deform the head and fix the shaft in place.”
Use 3mm brims for the vent body, since it has too small of a contact surface to stay stuck to the plate.
I found that I could print 6 of each of the print's four parts on a single Core One bed.
Order of Assembly:
- Place 2 cut pieces of filament into “Link” assembly.
- Use “Link” Assembly with the two extending pieces of filament to connect “Flap-A” and Flap-B" together.
- Position "Flap-B" (the smaller flap) on the side of the “Vent Body” tube where there is a little extruded notch/catch-piece.
- Place filament into “Vent Body” side holes and through the “Flap-A” and "Flap-B" side holes to secure them together with the “Vent Body.” (I do this by inserting a piece of filament, cutting it a little bit longer than the hole length with some flush cutters/pliers, and then using the flat edge of the flush cutter/pliers to push the filament the rest of the way into the hole)
Huge thanks to Simon Jin for this design, this solved an longtime annoyance/design flaw with my home AC-unit's non-directional vent outlets.
