Anet AM8 - 12mm Y axis upgrade

thingiverse

About ===== This upgrade aims to boost the stiffness of the AM8 Y Axis, ensuring compatibility with AM8 while increasing Y stiffness, particularly when utilizing longer Y rods for a 300x200 bed. My Y rods measure 480mm in length. I'm pairing these housings with the 12mm upgrade: https://www.thingiverse.com/thing:3016075 You may need to fabricate your own endstop bracket to get the stock Y endstop working properly. I've attached my rod holder for an optical endstop (made by BIQU) and my y endstop bracket for the optical endstop. BOM ==== In addition to the printed components, you'll require these parts: most of which should already be on your AM8: To assemble the rods: 2x 12mm linear rod in your desired length (same as frame depth) 8x screw for slot nut 8x slot nut 4x M3x20 ISO 4762 to secure rods 4x M3 DIN 934 nut To mount the linear bearing housings on the H plate: 16x M4x10 ISO 4762 screw (the stock anet a8 screws will fit) 16x M4 DIN 934 nut Remix & Sources ============== STEP sources are available in the files section.
