I like it! However, I don’t have a 350x350 build volume. Perhaps you could look at smaller build volumes?
Checked again. Fits on anything Ender3 Max or larger 310mm x 320mm+
Anything smaller and I would have to design in another cut, and connect those pieces with hardware.
Its possible, but its a good bit of design work, and may weaken the end result.
I have an ender 3 max, not in use right now, but I´ll take a look at it tomorrow. So I can print it and see if I can get the current version working.
