Kodama trinus filament guide

thingiverse

This small piece comes inbetween your extruder and the hotend and guides the filament properly into the hotend tube. It can help prevent the notorious clicking issue, which is caused by the big gap between the two parts. The filament tends to miss the entry of the hontend and is then stuck onto the edge of the tube. It also helps printing soft materials like TPE, which where unprintable for me since the material I used, tends to go inbetween the hotend and the extruder, due to the materials softness. It still happens if you print/extrude to fast, but atleast I can print TPE. Printing & Installation Disclaimer: I take no responsabilities for damaged printers or injuries! Try this at your own risk. I printed my guide out of PETG, since I didn't know how hot the tube of hotend can get. The filament I use can withstand up to 90°C and after several prints(up to 240°C) it still doesn't show any melting. You might have to sand the piece a bit after printing it, to clear any strings and I also had to clean the hole. Use a 5mm drill bit for the first 2.5mm starting from the bottom and then a 3mm drill bit to go through the hole. To install the the guide, you have to disassemble the print head, until you're left with the extruder and the hotend like in the picture above. Below the extruder are two threads with the grub screws, which hold the hotend in place. Unscrew them until the hotend comes loose and pull it out a bit, so that you can insert the filament guide. Now push the hotend back in so that the tube of the hotend gets into the guide. Screw the grub screws back in to fixate the hotend, but be very carefull to not to overtighten them, since you can damage the aluminum threads very easily. Now put the print head back together and enjoy inserting your filament on the first try (took me every time several minutes without the filament guide)!
