Human: Anycubic i3 Mega Extruder Modification for Flexible Filaments.\r\nIt employs an almost full bowden passthrough approach and adds variable tension adjustment capabilities.\r\nThe modification is easy to print and install on your 3D printer.\r\n\r\nMaterial Requirements:\r\n\r\n 4mm-2mm Teflon Bowden Tube and M10 Bowden Fittings (the inlet one is optional).\r\n You can find these at: https://www.aliexpress.com/item/3D-printer-accessories-V6-fast-connector-M10-pneumatic-quick-joint-bowden-tube/32880549566.html\r\n\r\n U604ZZ U-groove Bearing:\r\n Find this on: https://www.aliexpress.com/item/10Pcs-lot-3dPrinters-Extruder-Parts-U-groove-idler-pulley-belt-pulley-bearing-U604ZZ-u-ditch-604U/32818240686.html\r\n\r\n M3 Screw and Nut for the Tension Controller.\r\n\r\nUPDATE:\r\n Since using it with ABS, I can attest that it's working flawlessly. To achieve optimal results, adjust the tension according to filament type (80-90% for flexible and 15-25% for rigid filaments). A significant improvement is how easy it is to change the filament now due to the extruder wheel guiding it perfectly. Adding an inner PTFE tube allows you to attach the stock filament detector without a magnetic support.\r\n\r\n I've also added a knob grip to facilitate tension adjustment by hand, eliminating the need for a wrench.
