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

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.

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 can't use these, my printer isn't the right size, however I found someone who can. They are really easy to install, and would solve my issue. Word to the wise, confirm your hardware before you order.

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. I've replaced the stock Z-axis stop switch brackets with adjustable ones, might be something to do before adding these, they're probably not an exact height replacement.

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.

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 doesn't 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.

If you have a 3D printer you know how much of a pain it is to level the bed and 5-10 prints later re-level the bed... and 5-10 prints later re-level the bed... once I put these in it have not had to level my bed again and I have printed probably around 100 things! They work great on my Geeetech A10M and I will be getting another set for my Geeetech A10T!

Love these. Silver spring, yellow spring, now to silicone. I replaced the yellow springs and added these in their place. Leveled the bed and have not had to re-level it since installing them. It's been over a month now. They are a lot stiffer than the springs once you get them compressed. I believe the back pressure from these keeps the adjustemt wheels from backing off.This is my second set. The original set i put on an Ender 3. This set is going on my CR10S when it arrives.
