1.75/3mm filament guide

thingiverse

Human: A printable filament guide for directing filament through an IKEA LACK tabletop into an enclosed build chamber.\nI uploaded various designs, including circular and hexagonal tops in 1.75mm and 3mm versions, with filleted and nonfilleted options. For users who want to modify this design, I included the master .123d file containing every component used.\nSuggestions for improvement include:\nAdding 3-4 fins between the base and tube to prevent rotation without using glue.\nModifying the design so that the base and stem are separate parts, with a flat base attached to the main part via screws or glue. The "base" can be printed as desired and clipped onto (or glued) the tube.\nThe idea for this filament guide came from http://www.thingiverse.com/thing:1740538\nDimensions:\nCircle/hexagon diameter: 3 cm (design intent)\nCircle/hexagon height: 1 cm (design intent)\nTube length: 5 cm (design intent) (V2/1.75mm = 5.5 cm)\nTube outer diameter: 5 mm (design intent)\nTube inner diameter: approximately 2.4/3.25mm (design intent)\nFillet if applicable: "setting 2"\nTotal length: 6 cm (V2/1.75mm = 6.5 cm)\nTotal width (diameter): 3 cm\nPrint Settings:\nPrinter Brand: Prusa\nPrinter Model: Prusa Steel\nRafts: No\nSupports: No\nResolution: 200 um Z, 400 um xy\nInfill: 20%, but this may not be significant\nNotes:\nI printed the 1.75mm filleted versions in PLA. The tolerances on V1 were too tight, so I increased the inner tube diameter to accommodate slightly bent or oval filament without excessive friction.\nThe guides are intended to be printed standing on the broad base (dimensions have been corrected for smaller printed vertical holes). Printing in the length might result in less filament friction, but this will be tested first.\nI plan to print using ABS later at 10mm/s with an extruder temperature of 242C and a bed temperature of 80C. Cooling, temperature, and speed settings may need to be adjusted. A 400 um nozzle and 200 um layer height will be used.\nPost-Printing:\nThe guide is designed to be inserted into a 5mm hole drilled through the tabletop of an IKEA LACK table. Glue can be added if desired.
