Filament Guide Direct Drive

I needed a filament guide when I converted my ender 3 into micro swiss direct drive which had push-in couplings on both sides. So I could use my filament dryer.

Hardware Required: 2 x M6 Couplings Approx. 30mm of 4mm bowden tube.

When printed clean the 4mm holes with 4mm drill bit. I cleaned the bigger holes for the couplings with 5,5mm drill bit, but I maybe think that its easier making M6 thread in them.

Edit: 15-09-20 I uploaded a single push-in version
