6 pcs Bubble Spirit Level, 32x7mm Circular Level Bubble for RV, Travel Trailer, Tripod, Phonograph, Turntable

Got them for scope mounting,they should be perfect.thin enough to fit under scope on pic rail.

I purchased this set of 6 levels for "initial" leveling of my new 3D printer. Starting off with a level surface is important for any number of hobbies and in my case the immediate use was for setting up the rough level of a new 3D printer. These levels have a center target that gets you within about 1% of level and are easy to just set down on a print bed or frame for quick leveling. They are inexpensive and easy to see and use. While they do not have "any" type of adhesion this is perhaps better and faster in moving the level to various places around your project and makes it easy to slide them along an X or Y axis. The levels seem well made for the intended purpose and my intention was to actually attach these to the four corners of my printer on a permanent basis but I have not looked into how I would do that (glue, double stick tape, etc. ?) so in that regard perhaps a little disappointing in function. I would also suggest this for resin projects and wood projects as well.

This bubble levels are used in our manlift so that we can make sure all four legs are level. They work like a charm.I’m

They are large enough for an old man like me to read. I put one on a magnet to hold it to the bar of my chainsaw. I make the stumps perfectly level and use them for plant stands. I also hot glued one to my drill to help making vertical holes. I would buy them again.

There are 6 of them so I can use them in many areas. I use them in my trailer to make sure it is level.

These are ok if you don’t need exact precision. They all show the bubble kinda around the same spot, but not exactly the same.

As expected

For a totally different use, these are perfect for 3d printed level tools for Beyblade X launchers.(Yes, the kids toys, that are actually not for kids if you look at the prices.) This bubble level is perfect for helping with learning to angle launches.For the price, they are very worth it.You can find 3d print files all over that use this size bubble level.
