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

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.

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.

I havent had to level my bed since I got them months ago.

Awesome I hardly level now.

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.

So much better than using springs on your print bed.

These are fantastic. I don’t have to level my bed anymore. On the ender 3 pro the back left is a bit too big. This company is fantastic. They sent me a gift that cost more than my purchase. The gift did not influence this review. They are spacers not much to say other than they work great.

Springs are a challenge to keep level, but this will not let me level the bed at all. After fighting with for days trying to get them to work I ended up having to take them off and put the springs back on the bed so I could at least use the printer again.

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.

Work great
