Ender bed nut wheel

"Back to the old method"

Ender 3 family come with weak bed spring which make throw off leveling from time to time. Stronger yellow spring and silicone/rubber stud is great but I choose the odd way of using second nut to lock the bed in place.

This method completely lock the bed and it can never be moved from accident or vibration.

I feel that the person who started using spring suspended bed will be mad at me, because it's clearly an inefficient way. But I do think it's much more secure and relief my "the machinist who don't trust his reference surface syndrome".

This mod requires 8 extra M4 nuts in total, where 2 nuts are used for each corner:

1 nut to keep the screw firmly upright. **refer this https://youtu.be/v5u_Xgq62nQ?t=214
1 nut (in the wheel) to set the height of the bed.

the first nut is important and you should find out why once you start doing this mod.

At first, If's confusing to set the bed height, but you will get used to it.
