selfmade substitute for the springs beneath the printbed. Just print a cast and pour silicone in it :wink:

I intended to use for #SCOUTcorexy silicone pads on the screwheads that will contact the bed, I am so glad someone did it before me so I am not guessing anymore…

The only unknown I have is that when you are doing the leveling the silicone will twist because its not slippery on the bed, forming a spring that will naturally want to untwist after you are done. Can that cause loosing some percentage of the 100% leveling you just did?

The silicone isn’t twisting at all. It is enclosed by two fixed and not twisting sheets, so there is no way it can be twisted…

@Mark_Rehorst You are probably right, but the DICE gets as many features as possible :wink:

@Rene_Jurack
When you rotate the thumb isn’t the silicone trying to also rotate with it? Is the screw rotating inside the silicone hole without dragging the silicone with it?

I use silicone spacers for springs. I used a piece of tube I got for free as a sample in a hardware store. Printed a small rig for cutting it to four equal lengths. Maybe not as exact as your cast but a lot simpler. But of course I’m restricted to the dimensions available for tubes. Casting your own makes it possible for other sizes. My tube has 10mm outer diameter and 4mm inner. Used washers on each side to distribute the force.

@Florian_Ford the silicone don’t twist unless it can move freely. I secured the bolt with a nut at the heated bed. Adjusting the bed only makes the distance shorter and pushes the silicone together
