The ender 5 plus XL that I build for practicing my 3d cad modelling skill. The bed is 500mm and still use stock part of ender 5 plus.
Warning : This model isn't accurate so you must modify it if you want to modifying your ender 5 plus to have big heatbed.
Update 2 September 2023 : I added fusion 360 link preview. You can check at https://a360.co/3EpRZhz
