So far, adds the right amount of sturdy tension for leveling and maintaining a flat surface

I am really liking these springs, they have enough tension that they do not come loose very often at all.

They provide enough tension to keep the bed adjusted properly.

I no longer have to level my bed every other print, they have great tension and have not had to re-level my bed for close to a week now.

I cannot say enough how much I would recommend this company and this product

Thanks for a great product.

Excellent replacement spring

Superior replacement for springs on ender 3

I found these to be a perfect replacement for the stock bed springs on my Ender 3, 3d printer

Great replacement for Ender 3 bed springs

Great springs that instantly improved the print bed stability on my ender 3 pro.

Perfect for my Ender 3 Pro

Worked great on my Ender 3 - Pro

Excellent buy if you are purchasing these for a 3D Printer.

Definitely worth the purchase just for ease of use

Best purchase for my ender 3 pro ever.

Work great used on my tronxy s5 solved my issues

These things are great

I'm sure some engineer could correct me, but these seem to be about 2x as strong as the stock springs and when you are installing them and getting them ready for the first levelling of the bed, you can really tell that these are a big upgrade to your Ender 3, things are obviously way more stable and for the few weeks I have had them running, they seem to stay in place causing me to have to re-level less often.

I feel like I can dial things in a bit better and get nice first layers after doing so, but I've had to level the bed about the same amount if not more times after these springs

Hopefully these things didn't warp my bed.

; the thing no longer falls off level after every other mildly stuck print

What a game changer, my leveling nobs don't fall off mid print anymore and the leveling on my bed has been more consistent than ever before, I just wish I bought them sooner

So far, I have been getting consistent results leveling the bed on my Ender 3 Pro with these springs, the stock springs are way too mushy/soft for my taste and will lead to constant bed leveling issues, in my opinion

This really improved my Ender 3 performance, the extra stiffness was very needed to make possible a reliable bed leveling that also lasts longer.

So far zero problems, bed has stayed level for weeks, even when I have to pry prints off the bed when I got a little too enthusiastic with the hairspray

It is very consistent makes it easier to make fine adjustments when leveling

Solid, simple, stiff, Ender 3.

Solid, simple, stiff, Ender 3.

I didn't have my stock Ender 3 springs long enough to experience the bed leveling going out of alignment on its own, before replacing the stock springs with these

Upgraded my standard Ender 3 springs with these, and they seem to work great!

Springs work great on Ender 3

Springs work great

Springs were much stiffer than stock springs on Ender 3, work well with my glass bed after adjusting the Z stop

Also as a heads up, these Springs do not work for the extruder gear replacement Spring.

Springs were much stiffer than stock springs on Ender 3, work well with my glass bed after adjusting the Z stop

With the added spring tension the adjustment wheels for leveling the bed are also quite a bit more resistant to being adjusted & i highly doubt they will loosen even after hundreds of hours of print time

This really improved my Ender 3 performance, the extra stiffness was very needed to make possible a reliable bed leveling that also lasts longer.

These springs replace the flimsy bed springs that come in the Ender3

These work great bed level is far easier and consistent.
