I have tried a few ways to make a revise Bowden setup for my Prusa MK3s. 

This design requires only 220mm of 4mm OD PTFE tube to be bought, rest is printed.

(OD= outside diameter; ID=inside diameter)

I tried the 2mm ID but had difficulty pulling out the filament with the little ball of re-solidified filament so I went to 3mm id and now its perfect. I prefer the clear PTFE so you can spot any problems.

I still use the 2mm ID for my dry boxes, to keep the air out and also the ball then stops the filament going back too far.

The ptfe-screw-prusa is split in to two parts for ease of printing, just align them by putting PTFE tube in and glue them together with super glue.

I have also added the connector and the cap, incase you want to modify your existing dry boxes to this system.

See my other models, I am working on a DAISO 5.5l dry box project that goes with this design perfectly.
