This is a replacement cover for the PolyDryer that has integrated locks compatible with the Python AMS Enclosure. This modification requires no permanent changes to the PolyDryer, and the dryer can be returned to stock configuration at any time provided you save the replaced stock parts.

The mounting of a PolyDryer to the Python AMS Enclosure is a known weak point simply because the PolyDryer was never designed to support itself, but merely index to a dry box. This modification extends the PolyDryer interface to use the same slide-on locks that the Python AMS Enclosure uses for it's blanking plates.

Print Instructions

• This print has been tested with PLA, but any filament should work just fine. Heat is actually not much of a problem, as the dried air is not particularly hot and it doesn't contact the cover except at the very edge of the exit port.
• Print with the flat sides down, of course.

Print Quantities (per PolyDryer)

• 1× Cover
• 2× Ports
• 2× Rear Seals
• 4× Gaskets (optional)

Hardware:

• 8× M3×6 Socket Head Cap Screws

The Gaskets are the same gaskets as from the Gasketed Cutout Seals project above)

Assembly Instructions

1. Unscrew the four black screws from the PolyDryer case. They should be the only externally accessible screws and are located on the label side of the dryer.
    
2. Remove the stock cover, taking care not to disturb any wiring. The power connector is especially prone to wandering.
    
3. Remove the airflow cap from the inside of the removed stock cover by removing the four silver screws.
    
4. Attach the airflow cap to the printed Cover using the same four silver screws. Take care to keep the same orientation. The cap will key into raised features on the printed cover, but it is possible to force it into the incorrect orientation.
    
5. Screw the printed Cover in place on the PolyDryer using the same four black screws. Again, take care that all the wiring is kept in place and not pinched.
6. If desired, press a Gasket into the both sides of each Port.
    
7. Screw the Ports onto the outside of the Cover with the M3 screws, 4 per port.
    
8. Attach the PolyDryer to the enclosure by passing the Ports through the cutouts and then sliding a Rear Seal onto each Port from the inside. This will take a little bit of finesse and probably some force as the tolerances between the dryer ports and the enclosure cutouts are rather tight.

Hints

• When screwing into the printed part (attaching the airflow cap to the printed cover, or the printed cover to the PolyDryer), go slowly and use more than normal downward force.
  
  The printed material will almost certainly be harder than the stock plastic and there is a chance of splitting the printed parts if you move too fast. Splitting usually occurs along layer lines, so pressing down should help keep them together while the screw forms it's own threads. Some splitting (1-3 audible “cracks” per screw) is fine; the screws are rather long and only a few threads are required to securely attach the cover or the airflow cap.
   
• The ideal Port screw size is M3×6, but up to about 10mm will work fine. It can help to drive an M3 screw through the cover alone to form the threads before trying to attach the Ports.
   
• Again, the power connector is very prone to coming loose from the case, pay special attention to this during assembly.
   
• The fan and thermocouple (brown) wires both run along the top of the dryer and are easily pinched or damaged.
