Filament Tube Guide Holder

thingiverse

I use a 4mm O/D tube to guide my filaments, so I needed a holder that could do the job right. This holder guides the filament into the tube and takes it from the middle of the spool with ease. First, you'll need a single hex nut and bolt/washer that can fit into the existing hole in the back of my CTC. The print settings are as follows: Printer: My trusty CTC Rafts: I don't use them Supports: None needed Resolution: A high-quality 0.2mm Infill: A solid 20% for added strength Notes: This design prints in about 30 minutes using PLA, but be warned that there may be some minor warping around the hex nut holder if you don't give it enough time to cool between layers.
