I wanted to upgrade my Ender 5 with a BIGTREETECH TFT35 E3 V3.0 but it doesn't fit the frame. I didn't want to cut the steel frame so I searched for alternatives. This gave me some ideas. I remixed to fit the Ender 5 frame and added snap fittings to the frame hole and the top cover. Editing was done in tinkercad so there are some tiny leftove iide the case. The tolerances are tight so measure what you have and scale accordingly.
