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

Swapping the springs that came with my Mega S out for these was an instant game changer. I went from having to re-level the bed before every print to being able to basically ignore it. Only thing to keep in mind if you plan to do the same is that these are pretty short compared to the original springs - both Z-stops needed to be adjusted before the nozzle could actually reach the bed again.

keeps the platform more level longer

Everything perfect. I installed in my Ender 3 Pro, to replace the stock springs. They work just fine, they are a little too hard so you have to screw them tight. Maybe you will feel you lose a little fine tuning but I think is no a big problem. My bed is level and working fine so far.

I havent had to level my bed since I got them months ago.

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

Slightly varying dimensions but this did not affect the use of this product. Have used on my Wanhao Duplicator i3 Plus clone ( Monoprice Maker Select Plus ) and has worked very well for me. These hold better than the OEM springs and seem to reduce the bed wobble entirely. Have been using these in conjunction with an upgraded Y-carriage and 3-point bed leveling (makes leveling way easier) and have had much more consistent prints without having to worry about re-leveling as often. Have had no issues with heat from the bed, these seem unfazed by it.

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.

In my case the spacers were about 4mm to short to get good adjustment before they became to stiff. I had to use a few washers to raise one corner.

Great product and worked!

perfect replacement for the springs on ender 5 pro
