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 great as they stay where you set them. On a CR-10S, you need to use an adjustable z-axis endstop bracket or youll have to use shims as these are thicker than the stock springs.

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.

They have been a great replacement for my printer’s stock springs.

Installed on my Sainsmart Coreception 300 (https://www.amazon.com/dp/B089GMWCS8/ref=cm_sw_em_r_mt_dp_26MUFbSCA4S0Q?_encoding=UTF8&psc=1) I had high hopes for these. But I still have to tram the build plate between every print. I would say stick with the stock springs and save up for a BLtouch or EZABL.

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.

It was good while it lasted. Had it since Aug 2020. It lost it shape a bit.

Ill never have to level my bed again!

Had these on my ender 3 for about a month... Only needed to level it once since the initial setup. Highly reccomend for any stock printer, and an absolute must for BL touch or other mesh bed leveling users.

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.
