4PCS Upgraded Hand Twist Leveling Nut Diameter 22mm, 4PCS Hot Bed Spring, 4PCS M3X35mm Screws for 3D Printer ANYCUBIC Mega Hot Bed/Platform

No direct fit but working well, had to use the cogs flipped upside down so it won't jam itself with my printer structure.My printer is a He3D I3 acrylic body and precision z screw.

Just in case there is anyone else wondering if this will work to help them with there anycubic kobra neo it works! I can now manually adjust my bed. I was having issues with the bed not being level and auto leveling not being able to compensate enough with the stock stiff mounts. I did not want to shim or trim Any of the mounts and decided to go with this adjustable option instead. The hardware that was provided slipped right through the threaded hole of the stock screws and I was then able to thread the knobs on the bottom. I know have a nice and even first layer and good bed adhesion.

Knobs are to big the the Anet A8 to have total clearance. I had to run the screw in them attached them to my drill and grind them down. They work good now.

Exactly what I needed

I'm new to 3D printing and my first printer is the Anycubic Kobra Neo. From the start I had issues with bed leveling which auto leveling did not fix and was only solved with these springs/knobs so I could properly manually level (paper method). They make manual leveling so much easier and faster and I finally am getting good first layers and adhesion. I was almost completely discouraged from the idea of 3D printing due to the leveling issues, but now I'm loving it. Do yourself a favor and get these knobs. You will thank yourself.

I purchased these to upgrade the wing nuts on my 3D printer, and it turns out this is one of those small changes that can make a big difference in leveling your print bed. There's not much to say about them other than the quality is good, the nuts are comfortable and easy to adjust, the springs have have just the right amount of tension, and the screw heads fit flush with the top of the bed. I added hex nuts to the screws where they go through the bed to lock them in when adjust the knobs, but that's not really necessary.If I ever get another printer that doesn't have these, I'll definitely buy them again.

I does not fit my Tevo Tarantula. I was thinking the missing 5mm would be easy to adjust turns out my printer won't because of the brackets. If the length isn't an issue get them they are more than fine and better than waiting for China to ship. The bolts are countersunk as of 2.21.2021. The springs are shorter by 5mm in my case but it doesn't seem to matter for me going to have to adjust my z height but this is faster than saving 3 bucks and waiting for it from China.

For my Anet A8, I had to modify both the printer and the thumb screws. The printer modification would be required for any similar thumb screws. I'll explain that later in the review.I did find that the diameter of the thumb wheel was a little big and fouled out against the frame of the printer. I had to take the front two and use my bench grinder the make them smaller.To modify the printer:1. I removed the old screw / wingnut assembly from the printer.2. I then had to drill out the threaded holes in the carriage with a 1/8" drill bit. This allows the provided screws free movement in the carriage.3. Next, I installed the screws through the print bed, with a drop of thread lock and a washer and nut on the bottom of the bed. This way, the screw is firmly affixed to the bed.4. Finally, I put another washer and then the spring on the screw. This washer is between the nut and the spring, and provides a more even surface for the spring (so it's not pressing on the nut).5. I aligned the print bed up so the screws would protrude through the carriage.6. I added another washer below the carriage, and screwed on the thumb wheels. The washer is to help reduce friction between the wheel and the carriage, so it's easier to turn.

This set is probably great for the right printer, but it DOES NOT fit the Monoprice Maker Select V2 for the following reasons:1) The screws have a tapered head that will never fit a flush surface.2) They also don't come with nuts to secure them in place on the underside of the heated bed, which means that you would also need a screwdriver in addition to the knobs to level the bed to keep the screws from spinning.3) The knobs are too deep to fit the Monoprice Maker Select V2 and will make contact with the frame under the heated bed.4) The springs are too long, even when fully compressed. The hot end makes contact with the heated bed when fully adjusted in.Again, no issue with the product, but be aware it is NOT for the Maker Select V2

good

Super pour remplacer cela d'origine d'une imprimante anycubic méga pro

Preso il kit per una Anycubic Kobra neo, posso solo dire meno male....da quando l'ho montato....ho cominciato a stampare bene

I got these as replacements for the metal ones on my Monoprice Maker Select, unfortunately after fitting the bolts I had to put the originals back in because when I tightened these, they protruded too far down and rubbed off the chaise. Also I could only fit 3 of the wheels on that bed as the back left one was hitting the bolts on the back and wouldn’t cross them. But for what I got to use I was happy.
