Anet A8 Back Brace (minimal print) with threaded rod
thingiverse
We all know the A8 acrylic frame is woefully lacking in stiffness. Inspired by Photoberto's ingenious creation (https://www.thingiverse.com/thing:2351450), which utilizes M6/M8 rod to provide torsional support at the front of the frame, I sought a solution to its inflexibility. Upon installing this upgrade, I observed a noticeable flex in the frame across where the LCD is located. In response, I designed these inserts to fit snugly into the A8 cable management holes and accept an M8 threaded rod. When paired with some M8 rod and large washers, they provide necessary rigidity to the vertical supports, preventing them from bowing inward. A printable alternative exists (https://www.thingiverse.com/thing:2176224), but I prefer the added strength of threaded rod and not wasting precious time printing a potentially weak upgrade. I'm more than happy to modify for other rod sizes if needed. Feedback is also welcome. Each plug measures 25mm in diameter, 8mm in height, with an M8 compatible hole.
