Awesome upgrade for my Ender-5! It is much more stable now. Very nice design! You won't believe how much support these brackets add to your platform.
Be careful when tightening down your bolts. I cracked the left support when attaching the backside clamp to the main part. I'll be printing out another one. I know I shouldn't have used PLA but that's all I had. I'll be printing them in PETG soon. Jumpshoutmedia suggests this in his description and I should have listened. Lesson learned.
