Dual Extruder single hotend remix help

I am looking at setting up a dual extruder single hotend setup and useing this dual extruder looks like the best bet for a starting point:

Now the changes I want to make:

1) change the exit for the connection to fit more standard Pneumatic Fittings PC4-M6 type [www.aliexpress.com]
2) Change the top input to have an integrated filament sensor on both.
3) Change the top top input to accept the same PC4-M6 fitting as the desired output.
4) a fitting system to allow for connection to 2020 or 3030 frame extrusion.

I have tried for a week to figure out how to do this but my skills are way lacking....
Anyone able to do this and help out? I have no $ to put to it... no clue how to use OpenScad [www.openscad.org]

I imported the STL into sketchup and cleaned it up and tried after that for days with no luck.

Hopeing someone might want to do the remix and release it all theirs, I just want the part

Thanx regardless.

I managed to do it myself but I found out this was actually a remix of the Prusa i3 MK2/S to Multi Material upgrade seen here.

[manual.prusa3d.com]

So I don't know if this remix is permitted and I wont post it until I know it is.

That said I am pretty happy how it came out optic filament sensors on each feed...

Prusa I3 mk2/3 is open source, so remixs are fine... as long as they give credit where its due..

Thanx Dust
