ANET A8 Back Brace (rear Y axis)

**Critical** accuracy is essential for prints of this magnitude, and if you're experiencing problems with belt tension or damage to the belt, your accuracy may be compromised. Unless you've made changes, you should be using standard X/Y calibration settings. A crucial adjustment was made to the source part, adding a second support for the motor. This provides vital support for rotational moments and helps reduce strain on the main mounting, which I was concerned might twist over time. Additionally, screw holes were added for the back acrylic (though their location wasn't ideal in my print - it should be better now). It's likely that more support here won't cause any harm, and I planned to tap and use long M3 bolts for increased stiffness. The corners were also mitered to ensure a smoother fit on the bed. This has the advantage of providing some flexibility with dimensions, but you still need to stay within 1-2% tolerance. Holes in the base were intended to increase strength. The print was done at 6.30, with a layer height of 0.32mm. No support was needed (I increased the angle of the hex hole for improved printing, and the slots should be fine at 45 degrees). 09 Oct 2017: Version 2 was added, featuring a slot to adjust the drive gear position. 21 Oct 2017: Version 3 was introduced, with a lower rear-left corner designed to avoid catching on bed insulation.
