If you are thinking about getting a 3D printer, calipers are an essential tool if you want to do things like make replacement parts or measure the prints you make. This is a great set of entry-level digital calipers for use in your workshop or makerspace. Once you own a set of calipers you will truly wonder how you were able to function without them. These work well for everyday measurements of thickness, internal diameter or gaps that you simply cannot measure with a ruler. You can switch from standard to metric with the simple press of a button.
Sold with case and 2 LR44 batteries as well.
