EIBOS Polyphemus Lid tray mod with closable ECAS PTFE mounts

Using the Polyphemus  "as is" is quite disconforting. I wanted to improve usability.
 

Putting the whole lid + expansion to pieces, I assembled it in reverse, putting the expansion on the top, and not the bottom.

I modeled the frame part so I could have a working basis for some more mods I may or may not do later. 
If need be, feel free to use the CAD of the Frame Lid

I made a small panel to replace one of the expansion's acrylic panel, providing 3 filament outputes with ECAS PTFE mounts. I addes some 6x3mm magnets to provide caps on the unused filament outputs.

I modelled a new top lid assembly, where one could mount the stock Polyphemus top panel and the handle. 

The top lid can also be used as a small tray, as it will have some small borders for light objects not to fall down.

I now have a more functionnal Polyphemus

BOM:

• 6x M3 5x4mm heat inserts
• 6 6x3mm magnets
• 4 M3x12 Countersunk screws (should also work with SHBS or SHCS)
• 2x M3x16 SHCS for the handle
• 3 ECAS
• A big enought printer (printed mine on a Voron 2.4 350, should also work on a Voron 2.4 300)
   

Lid Assembly:

• Mount magnets and ECAS on the printed panel
• Invert the extension and the main lid parts to have the extension on top, do not use the top panel
• Replace 1 small panel with the printed panel

• Place the heated inserts on the bottom lid part
• Place the pins on the top lid parts (mostly at the mid places, as they are no screws there)
• Assemble the top lid part to the bottom
• Slide the top Polyphemus panel inside the top lid, and mount using M3x12
• Mount the handle using M3x16
