Imdinnogo BCZAMD Heatbed Silicone Leveling Column, 3D Printer Hot Bed Mounts Column Stable Tool Heat-Resistant Silicone Buffer for Prusa i3 Plus A8 Wanhao D9 Mega, 4 Pack Brown

Ive went from the stock springs on my ender 3 to the yellow upgrade springs, to these. If you compress them quite a bit then set your Z stop switch so that when leveled they are about half compressed- then they hold level amazingly well. Been running them for some time and level stays put. I like them.

With the OEM spring things under the bed of my Anycubic Mega S, I had the level the bed with pretty much every print I did. These little fellas install easily and keep the screw from moving, so I rarely have to level the bed. Maybe once every 15-20 prints or so just to make sure things are still in good shape. They are inexpensive, look sharp and work well.

I originally upgraded to the yellow springs on my Ender 3 v2 but found that I still had to constantly level the bed. With these silicone spacers I am able to set the bed and not have to level it so often. I check it about once every dozen prints and it doesnt need much adjusting. The spacers are much sturdier than the springs, and keep the tension on the bed without loosening much better than even the yellow springs.

Consistent level lasting over more prints! I hate bed springs.

They have been a great replacement for my printer’s stock springs.

Inconsistent height and diameters. Returning

Great addition. Have them on each of my 3 printers.

while they do function the 16mm height was just not enough for my CR-10s. even after adjusting the zstop limit switch the wheels were too loose to level properly. I ended up having to use 4-5 washers to shim the bed up. after the workaround it has been printing great not noticing any bed level issues after many prints. If you have a cr-10 I would recommend columns 20+mm

Had to re-level my bed after every print with these, was not impressed. I ended up swapping back to the stock springs and havent had to level in close to a month.

Was not able to use. Had to remove them and put springs back on. I have the Anycubic i3 mega S and these did not work on my printer. They were not tall enough for it to level bed out. They were to small so I wouldnt recommend for this printer if its stock.
