This is a great kit for anyone upgrading or modifying their 3D printer. I removed the power supply/controller from the base of my Ender 5 and am using them to support the corners as the power supply was used for support (photos to come later). I've noticed that other sellers sell these mounts but don't include the hardware (bolts and t-nuts) to mount them. This Aimengda set has EVERYTHING you need, even an Allen key! I am very satisfied with all BCZAMD purchases from Aimengda; They are reliable and provide instant customer support when needed. Very friendly seller with low prices; You did my business.
