Spacer nắp Eibos Polyphemus gắn fitting PC4-M10

UPDATE 06/08/2024: 

• Added a version without the threaded ports as per a request.

This remix of the original Eibos Polyphemus 3kg extension frame adds ports for PC4-M10 pneumatic fittings and a lip on top to keep the dryer lid in place. 

I made this to make it easier to frequently change where I have my PTFE tube coming out from while adding the ability to fit taller spools inside the dryer. While the Polyphemus allows installing PTFE tubes through the base instead of through the lid like the Cyclopes, I prefer using the pneumatic fittings for PTFE tubes. They're also easier to install plugs in to help keep the heat inside the dryer going up towards the vent in the top.

I printed mine using ABS to handle the heat of the dryer. I printed this with no supports, so I would imagine that most printers would also be able to do the same.

The print settings that I used were:

• .4mm nozzle
• .2mm layer height
• 4 perimeters (walls)
• 5 top and 4 bottom layers
• 20% Cubic infill
• no brim

The extension frame consists of only one model that is printed twice. Once printed, just flip them opposite directions and slot them together. They were a slightly tight fit, but once lined up slipped together nicely. I added a dab of superglue for peace of mind, but it's not needed.

I suggest printing plugs for any ports that you won't be using. This is because the fan blows the heat towards the front and rear of the dryer. In other words, right towards the ports. Plugs that I used for blocking ports with no fittings installed can be found here. Plugs that I used to block the pneumatic fittings can be found here. I also plan to plug the original PTFE tube slots in the base since there is a lot of hot air that leaks out from them.

I've included an .stl, .3mf and a .step version of the model.
