STRONG and FULLY 3D Printed Arms for your Ender 3 KE and SE

This is the fifth video on this printer, and we’re nearly there with the upgrades to get this printer printing like a dream. One thing that’s been bothering me is the amount of flex in the posts and the vibration I was seeing during printing. There have been a lot of complaints about how square the posts are to the bed, so I thought it was worth a closer look to see if we can fix both problems at once. The goal was to come up with something that looks good, adds the rigidity we need, and also allows some adjustment.
