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

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

Great product. But too short for my bed.

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.

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.

So much better than using springs on your print bed.

Less bed leveling

so far these have worked. Bed stays strong and leveled. Havent ran into any issues so far

These were used on a Wanhao I3 Duplicator Plus, all are the same height. This last batch I got some 3/4 x 1/8 hole fender washers from Ace and stuck them underneath next to the carriage, the edges of the columns bulged off the corners. Gives a much more stable platen than the original springs, even after adding spring cups and washers. Only time I need to level now is after taking the glass off to clean the gunk off. Price seems high for what they are but it would cost a lot more to get set up to cast my own. Have had no problems with the material even running 70-80 C bed temps with the plate glass with ABS. Running these on two printers. Ive replaced the stock Z-axis stop switch brackets with adjustable ones, might be something to do before adding these, theyre probably not an exact height replacement.

Got these to replace my original bed springs. Now I spend much less time leveling my bed. Once you get level, you wont need to re-adjust for quite a while. Really Glad I bought these.

Installed, leveled the bed and have not had to touch it since. I print almost daily.
