filament guide for ender 3

cults3d

Version 2.1 following the use of the filament guide made by another person for the creality Ender 3, I encountered a problem due to some very strong impressions. the filament that passes through the holding ring, machines (like a saw) this part in the long term (see picture of the part with the broken guide. having as a habit to design something that lasts over time, I looked into the question and I therefore made a guide that according to my calculations will last as long as the printer (no need to change it) Note: you will have to buy two small parts (or design them), but given the cost, and since I also have another project for this printer, you might as well buy. In short, so the new version of the filament guide is equipped with a "V" guide bearing as well as the thread to receive the screw that will hold the bearing. precision: I added chamfers on the joints to reinforce the whole thing! link: V-bearing https://www.amazon.fr/gp/product/B07CSWPHY2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 => Carbon Steel Ball Bearing Pulley for Rail Linear Track Systems 4 * 13 * 6mm
