What 3D printer do you have, in market for one..? Love your simple project and how you went about building it!!
I think the current recommendation is either an Ender 3 (for a budget one) or an Ender 5 Pro (if you can afford something a bit better). I would recommend the 5, it looks much sturdier. You might want to eventually add a BLTouch so it automatically levels, and you definitely definitely want to get the "silent" package (it really is entirely silent), the normal one makes way too much noise.
