Assembling the Ender 3 frame the right way | Keep it square and aligned !

In this video I will re-assemble my Ender 3 frame as part of my Ender 3 rebuild and upgrade project. It is very important to keep the frame aligned and square so your prints are not skewed and your rails don't bind. You need very basic tools, most of which are already provided with the printer. The key points when assembling the frame are: 1) All extrusions should be at right angles to each other. 2) The z axis pillars need to be parallel. 3) The spacing between the pillars needs to the same at the top and bottom. In addition to properly assembling the frame, I also added two upgrades: 1) Right angle plates to increase the rigidity of the z axis pillars. 2) Corner connectors to make the y axis extrusion more rigid. Parts I used: Corner plate L type: https://www.aliexpress.com/item/10050... Corner connector: https://www.aliexpress.com/item/33026... BLV kit for Ender 3 Pro: https://www.aliexpress.com/item/10050... In the next video I will install the BLV linear rails kit onto this frame. Thanks for watching.
