    Saw someone on YouTube and sounded a good idea to me. I have 2 Ender-3 Pros, one has these installed, the other is waiting until I complete a big batch of prints. In theory installation should be easy - dismantle, replace springs, put everything back together - unfortunately it my not be depending on your printer. The glue on the back of the magnetic bed was all that was stopping the bolts from turning and, because the height of the head of the bolts is slightly less then the thickness of the aluminium plate, it it easy to pull them off that glue and then they spin freely. To overcome this I pressed down on the magnetic sheet with my finger to mark a round indent, then cut an X with a very sharp blade, and peeled it back like an orange. I was then able to use a philips screwdriver in the top of the bolt to stop it spinning, temporarily. To stop it spinning again with everything reassembled you first have to add a nut on the underside of the bed, preferably with a non-metal washer (avoid scratching the paint on the underside which insulates the heater tracks/wires and causing a short), ideally use nylok (locking) nuts. It only took a couple of hours to do. There is another pack available where they are all the same length, if you have a cable relief system like an Ender-3 or somthing else that mounts around one of the levelling screws you need this one. Bed is as easily levelled and doesn't need to be readjusted as often as with springs (I've only done it when I had to adjust the eccentric nut on the Y-axis which meant the bed wasn't as level to begin with). I also found, with springs, that it wouldn't always be level after removing and reinstalling the print surface (probably once in every 3 or 4 prints I would have to relevel the bed) - no need to do this anymore! You may need to change your Z-endstop, depending on how much height you gain or lose, however I have upgraded to an original BLTouch which is used as the endstop so this doesn't matter.

    So far so good. Before I installed these "bushings", I had stock springs and washers below them. I checked that these silicone ones are shorter than springs, so I left the washers below them. And of course, looking from the Ender 3 control panel side, the left rear one, you must install the shorter bushing (1 piece only). Important!!! I'm not sure which way these should be installed. The other side has a smaller hole and other one a larger hole. I could not find any information from the internet about this, but looking at couple of pics, it seemed that the larger hole end goes towards the heating bed. I'm not sure but this is the way I installed these. They work fine and you can feel that the screwing is harder to do, as these bushings are quite sturdy. I don't have auto leveling and these things work without any additional tinkering.
