Hotbed Nut
thingiverse
I liked the idea of this hotbed nut: https://www.thingiverse.com/thing:2353642 However, I noticed that this nut doesn't fit to my hotbed. I guess, there was a new version of the Anycubic i3 Mega Ultrabase released. My version is similar to BETLOG's design but fits to the new nut format. As you can see from the pictures I'm not (yet) an expert of 3D printing :-D So I recommend to print one nut first and check if it fits, otherwise scale the model a little bit. This hotbed nut design doesn't need any additional screws, just the already existing nuts.
