Prusa MK3s/+ Bowden Tube Guides

thingiverse

This is a bowden tube guide, for those waxy 4mm tubes generally used in the heatsinks and bowden feed systems. So I made the SPANNERHANDS dry box and wanted to use the bowden tube to better direct the filament while reducing the flow of air into the box, but needed a way to direct the tube to where I wanted. I also wanted to continue to use the direct drive system I am using. Print this out of flex and attach to the frame. If you print this out of anything but flex, and a stiffer one, you are gonna have a bad time. The tube is a super snug fit, there is no tolerance accounted for in this design. Note the Vertical guide doesnt have the stopper so the tube goes all the way through for people with the bowden feed, the termination is intended for people who want to end the tube there and feed the filament to a direct drive. I printed with PRILINE TPU 1.75mm.
