Bondtech - Improved extruder lid with support for dual bowden fittings

I'm assembling a clone BMG extruder with parts bought from trianglelab on aliexpress.

I want bowden fittings on both ends so that i can chain a filament cleaner and a runout sensor before the extruder, and also because i have planned to build a heated drybox with bowden fitting to print nylon filament without ever having to expose it to moisture.

In addition to adding the 2nd pneumatic fitting recess, I added an arrow on the back so that people won't get confused about what direction it
