Nozzle cleaner (0.35mm nozzle)

thingiverse

Human: The Vertex K8400 printer's maintenance instructions suggest using a guitar string to unblock the nozzle when needed, specifying one with a diameter of 0.35 millimeters as the ideal choice. Although this tool has yet to be utilized, its presence serves as an added precaution for when blockages do occur. In these situations, I've discovered that gently pushing some filament through a heated nozzle effectively resolves clogs without needing specialized equipment like a guitar string tool. Nonetheless, preparing in advance can alleviate stress and make future repairs more efficient. To construct this improvised instrument, an 0.330 millimeter steel guitar string was acquired and stretched into the handle before being secured with heat from a soldering iron, though it's uncertain whether additional glue is actually necessary. In order to prevent damage while storing or handling the tool, a protective cover was devised that takes dimensional variances in the Vertex's measurements into account. Inner dimensions typically fall short of their designed counterparts; therefore, adjustments should be made according to each printer model's specifics, if needed. No modifications have been made with this tool since its inception; consequently, user experiences may potentially lead to future improvements. Printer Settings: Rafts: No specific requirements apply. Supports: No need for supports. Resolution: Opt for a setting of 0.2 for ideal results. Infill: 15% or higher can produce desirable outcomes; 30% was used here but could likely be reduced further. Notes: Personal preference governs settings here. The tool isn't demanding due to the inherent flexibility it offers. Post-Manufacturing Steps: Install the guitar string into the holder by threading it through and locking it firmly in place using a soldering iron (apply gentle heat). To maintain string length below 75 millimeters, snip the end near this measurement threshold, as any excess length might hinder proper fitment within the protective casing.
