support for PTFE tube

pinshape

After repeatedly swapping out filaments, I discovered that when introducing new filament into the bowden extruder, it would consistently get stuck inside, but this was clearly due to a faulty connection. During printing, I noticed an unusual noise emanating from the drive gear as it attempted to push the filament through the PTFE tube. Initially, I suspected clogging might be the culprit, so I thoroughly cleaned the extruder. However, even after doing so, the noise persisted. It wasn't until I observed how other 3D printers produced a smooth, curved shape that I realized my own printer's spline was to blame. By incorporating this support, the filament remains perfectly positioned, allowing it to easily flow into the extruder without ever getting stuck. In addition, I modified the filament diameter from 1.75mm to 1.67mm within the slicer software after accurately measuring it with a caliper. I created two distinct versions: one that connects via an 18mm tube marker and another entirely constructed from filament.
