Space Pi4 improved Bowden connection

I want to prevent the bowden tubes to enter the Space Pi box and avoid known issues.

This is a design thought to modify the Space Pi4 dryer without irreversible changes to the box. No need to drill, glue or disassemble the box.
The only thing is that you need to remove the existing inserts (I had one loose).

See details and explanations in the attached pdf file.

Due to some dimensional constrains the inner part is no robust as I would like, so, assemble and disassemble carefully and do not apply torque.

I tested with good results using PETG and ABS

Either way, make sure you have a good profile for the filament your intend to used.

Print the parts as placed in the 3mf file. No supports needed.
I used 0.4mm nozzle and 0.12mm layer height to get best definition in threads and smaller features. And print slooow. 30-50mm/s.

In the end, I always need to clear some burrs on the inner diameters of the Outer Part.

Hope someone finds this usefull.
