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

These are way better than the springs that come with the printer. I was constantly having to level my bed before I installed these. After installing these I have rechecked the level several times and it’s been perfect!!

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.

Ive only had to re-level my bed once since Ive installed these, and that was because I changed print surfaces (from the garbage glass sheet it came with to a spring steel PEI coated sheet). Liked these so much, I purchased a set for my CR-10s (this specific item) and my Ender 5. :)

I really like these over springs, this is a product I could see buying for every printer that has springs to level its bed.

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

So much better than using springs on your print bed.

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!

These are much more stable than the stock springs on my Monoprice Maker Select V2. I have not had to relieved for nearly a month since installing these, compared to every other day with the springs.

I put these on my Ender 3 pro, and I havent had to adjust my bed since.

This product has less to do with leveling your print bed and much more to do with keeping it level. Springs are tough to keep stable - even the good quality yellow ones. Silicone doesnt care about hot or cold, or humidity or anything else. These are so much stiffer and more stable than springs - wish I would have found this product sooner.
