BIQU 2in1 hotend STEP model

It's just a model of BIQU 2in1 hotend which I designed for developing all attachments.

Please note that manufacturer stated it as CR10 compatible. But inspite it looks qite close to CR10, it has lots of differences. It's a bit bigger, it has another throat and nozzle.

But the must urgent is the distance between holes for fixing it to E-plate is 15mm instead of 14mm which CR10 actually has.

That's why I attached two versions - real one with 15mm distance and 14mm version which is compatible with E-plate.

I had to widen the holes to set up this hotend to my Ender-3.

I designed only the radiator. The other parts I took from the model of CR10 hotend which I found on this site. And I didn't try to make all inside details due to they don't matter when you design a printing head.
