About this 3D model

I POSTED A PIC Of 2 MONTHS OF USE WITH THE A1 SERIES BOWDEN TUBE SET UP WITH THE 4 WAY HUB. THE PTFE TUBES GET SHREDDED AFTER ONLY A SHORT TIME SO THIS KEEPS THE TUBES STRAIGHT AND GROUPED TOGETHER IN ONE STRONGER BUNCH , DONT FLOP AROUND AT THE BASE ANYMORE AND ARE PROTECTED. I hope to not change out the tubes every two months that’s a waste THIS ALSO FIXES THE ANGLE THE FILAMENT ENTERS INTO THE TOOL HEAD KEEPING THOSE MUTICOLOR PRINTS RUNNING SMOOTHLY THIS WAS DESIGNED USING PLA . So other materials might be a tighter fit . If finding it too tight you can always scale up half a percent :) !! Can be used on any of the a1 printers. Internal id is 9.2mm
