Geeetech extruder idler arm
thingiverse
My Geeetech A10M's extruder idler arms are broken, so I designed a new one to replace them. Use something strong and hard enough filament. My choice was Phialment's Glass reinforced PLA: https://philament.hu/en/termek/philament-glass-reinforced/ Note: The hole for the motor axis is 6mm, so you should use the metal tube from original idler arm. (I heated up the arm, and when it melted, I pushed out the metal with a bigger phillips screwdriver. Tip me: https://paypal.me/pools/c/8kPoXIAxHI
